What is RAM?

Random Access Memory, or RAM, is a way for your computer to store temporary data, rather than in a cache or permanent storage. Storage, often wrongly referred to as memory, is permanent data stored on a hard drive or solid state drive. A CPU cache is a small amount of often-needed memory that is stored on a CPU chip. Both the RAM and CPU cache are temporary data stores that are cleared when your computer is turned off.

One way to think of the difference between these different types of storage is to imagine them as paper documents. The cache is a list of names or numbers you constantly refer to and keep close at hand. A folder full of papers you may need for your current task is similar to computer memory or RAM. The file cabinet full of folders for all your projects is like the storage on your hard drive.

Memory problems are less common than other computer problems because memory sticks have no moving parts and thus fewer points of failure. However, due to this many RAM problems go undiagnosed. Memory usually will last longer than other computer components so manufacturers offer longer warranties for it than other parts. If you buy brand name memory it will likely have a lifetime warranty.

Symptoms of a RAM Problem

  • When you first turn on your computer it runs fine, but as you go about your business you notice that its performance diminishes. By lunch time, websites take minutes to load and local programs run at a snail's pace. This type of gradual deterioration of PC performance, especially with memory-intensive programs, may be caused by a RAM problem.
  • Your computer randomly restarts while you are in the middle of something or freeze sporadically. It may also reboot almost immediately upon opening the desktop. This could be a sign of faulty RAM.
  • A blue screen with white text flashes before restarting. Blue-screen errors are annoying because you don't even have a chance to read the error message. Bad RAM is one thing that cause them.
  • Files—particularly ones you frequently access and save—seem to be inexplicably corrupted. RAM issues can lead to this problem, which can worsen over time. The file structure of your hard drive may slowly degenerate and you will no longer be able to boot your machine.
  • Your attempts to install a new program repeatedly fail for unknown reasons. You try to reinstall the operating system, but keep getting odd error messages.

There are certainly a variety of problems that could cause the issues above, but faulty RAM is an often-overlooked root cause of inexplicable issues. If you have one or a combination of the above problems you are likely facing a memory issue.

What Causes Memory Damage?

  • Power surges can damage most computer components, including RAM. You should plug your computer and other expensive electronics into a surge protector. Make sure you know the difference between a surge protector and a power strip.
  • Before you handle any parts in your computer, make sure you ground yourself by touching a piece of grounded metal to discharge static electricity. Electrostatic discharge can damage your computer.
  • Excessive heat can cause RAM and other parts to wear out over time. Individual components can overheat, or heat from one component can cause damage to adjacent parts.
  • If you have overclocked any part of your computer incorrectly, it may cause damage in the form of excess heat.
  • Your memory module may have some fault that passed through quality control and worsened over time. This is the most likely cause behind a damaged RAM.

It is also possible that the memory module is fine, but one or more memory slots on your motherboard are defective, hindering the RAM's performance. The defect may even be so bad that it damages the memory stick.

Diagnosing the Problem

  • If the symptoms started after you recently added more memory, the new module could be faulty. This seems obvious, but any time a problem begins after making a change, first check to see if the change caused the problem.
  • Your computer may produce multiple beeps or a continuous beep when you turn it on. These beeps can indicate many different problems, including being a symptom of bad RAM. Beep codes vary depending on the manufacturer of your BIOS. You can look up the beep codes for your specific computer to figure out its specific problem.
  • If you are not comfortable fixing your computer yourself, I recommend taking your computer to a local repair store rather than a big retail store. Big stores are in the business of selling additional parts, not fixing problems.
  • If you are an advanced user, there are diagnostic programs that can help you figure out if you have a memory problem. Your computer may have one pre-installed by the manufacturer or you can download a third-party program. The Windows Memory Diagnostic by Microsoft is also good if you suspect memory problems on a Windows PC.
  • If the above programs indicate your memory sticks are functioning, but you still suspect a RAM problem or if you need to find which memory module is the problem, you can try removing the modules and placing them in different slots.

Installed RAM

What installed memory modules look like.

Memory modules, pictured in the image above, are small circuit boards that lay perpendicular to the motherboard. Note that I removed many of the other components to make the memory more visible. If your computer has more than one module you should remove all of them except one and then run the diagnostic tests above or perform the task that normally causes the problem.

Fixing the Problem by Removing Memory

  • To remove a RAM module you need to press the tiny levers on each end to release it.
  • Test each of your memory modules one at a time to find which ones are bad. When you find the sticks that are bad you can order replacements. It is possible all the memory modules are damaged if your computer experienced a serious power surge.
  • If all the memory modules appear bad, then the problem is likely with the memory slot itself. Try testing each memory module in each of the memory slots to find if one of the slots is faulty. To fix a faulty slot you would need to replace your motherboard.
  • When replacing a module, make sure the indention on the bottom is lined up correctly with the slot and then press it in until you hear the levers snap. Note that some levers do not make a snapping sound.

Other Possible Problems

RAM problems often go undiagnosed, but they also can be misdiagnosed. Some common problems that have nothing to do with memory can cause the symptoms listed above:

  • Many of the symptoms listed above can actually be caused by a hard drive problem. You can run a utility called CHKDSK by pressing the Windows button and R at the same time, typing CHKDSK into the dialog box, and pressing enter. Alternatively, you can click on Computer, right-click the drive you intend to scan, click Properties, then the Tools tab, and click Check now. Note you will need to restart your computer. Also, be aware this process may take an extended amount of time to finish running. If you hear your hard drive making lots of noise during normal operation, it may be the cause of your problems. Defragmenting your drive every few months is a good idea as well.
  • If the performance problems occur during graphic-intensive programs such as games or rendering, your graphics driver could be outdated. Be sure to always keep your drivers up to date.
  • Excessive heat in your machine can cause a variety of problems.
  • Random reboots can be cause by a failing power supply.
  • Dirt and dust can also cause issues that look like memory problems. It is a good idea to clean dust out of your computer at least once a year, more often if you have furry pets.
  • Your computer can also have a virus. Note that many people automatically assume any problem with their computer is caused by a virus and many large retail repair stores frequently misdiagnose hardware problems as viruses. Make sure you have a good anti-virus program and run scans on a regular basis.

      Very helpful hub. My computer slows down quite often after a couple hours of use, which I at first just attributed to overheating, but even with a cooling pad it does the same. I think I'm going to look deeper into the problem.

      Nice article but my question to this is this. Can a dirty motherboard or even say dust or what not cause a memory slot to not detect the ram or cause it to not function as it should. My issue is what was said in this article but I have done all the steps and more and have not really found the cause. However when removing the ram I did notice that there was dust down in the slot which I am wondering could be the reason. Btw both sticks of ram display in bios and both sticks are brand new and tested with memtest program which came back good. The hard drive was checked with windows scan disk as well as the western digitial test and the hard drive is good. CPU is not over heating nor is the motherboard cause I check my temps on that often. The only reason I can see is dust.

      entreri28 4 years ago from Joplin, MO


      It could possibly be dust. Compressed air works well for removing dust. Just don't hold the can of compressed air upside down and not too close to the objects you are blowing. If your computer is very dusty you may want to do this outdoors.

      It sounds like your RAM is working if it shows in BIOS and memtest. What is the problem you are having exactly?

      Windows Memory Diagnostic says my computer has a memory problem. I've run virus checks using Microsoft Security Essentials but that comes up with nothing, so I think it's because my laptop is overheating. How do I get rid of the memory problem, and if overheating is the cause, would getting a cooling pad stop it from happening again?

    • profile image

      entreri28 3 years ago from Joplin, MO

      If your laptop is overheating that would certainly be the first that I would suspect is causing you problems. If you have had your laptop for more than a year I would clean it, or take it somewhere to have them clean it. Excessive dust can cause it to overheat.

      If your laptop is not that old, or you have cleaned it recently, a cooling pad will probably help.

      Hi, i'm hoping someone can help me. I recently took my PC to a computer tech guy I know. I suspected the hard drive had crashed, which he confirmed. But do hard drive crashes completely damage RAM? My PC had 8gigs and this guy said he had to put new RAM and all he had available was a little under 1 gig. ONE GIG! So I have a PC with a new hard drive, but now I can't even use it much because it's somewhat slow. I'm kind of back to square one. :( Please help.

      A hard drive crash should have no effect on your RAM. If you hard drive crash was caused by an electrical shock, dropping the computer or some other form of physical damage then it is possible both were damaged.

      Why would a RAM problem make a computer run more slowly as the day goes by?

    • profile image

      entreri28 3 years ago from Joplin, MO

      Throughout the day you will probably use various programs and some leave part of the program running in the background after you close it. This takes up available memory.

      So as the day goes on, more and more demand is put on your memory. If your memory is a weak point, either due to a fault or just having too little, your computer may slow down.

      If your computer becomes slower as the day goes on, it may also be malicious software that expands to take up memory. Be sure to run your security scans.

      I would recommend that you first clean your system for dust if you can. Next start your system and press the windows key and R at the same time. It will bring up a small box. Type msconfig in the box and press enter. That will bring up a menu where you can disable unneeded startup programs.

      It is hard to say what is slowing your system down. The tips above will probably help at least some.

      Hi, 2 nights ago I was playing a graphics intensive game when my 2 year old laptop screen suddenly went black and then restarted itself. I thought it was the usual static/black screen error so I proceeded to do this:

      1)unplug laptop and remove battery

      2)press on the power button for 15 secs

      3) let the computer cool for 1 hour

      4)start the laptop

      However, 5 seconds after I opened the game, my laptop screen turned black and restarted itself. However, now my laptop became noticeably slower. I then tried opening a web browser to seek an explanation an fill in an RMA. But 5 minutes later my screen went black and restarted again. This would keep occurring whenever I tried again.

      However, I noticed that if I leave my laptop on but idle with no programs running, nothing will happen and everything seems normal.

      I then downloaded the newest Nvidia driver, but the same thing happened to me (black screen then restart when 10s into game, 5 mins into browser, nothing if idle)

      I then proceeded to disable my Nvidia graphics card, and something even more alarming happened: 1 minute after I disabled the graphics card, my screen would freeze, turn white but you could still hear the normal functioning sounds. I can't remember if the computer would crash after this.

      I think I should mention here that I just had my computer sent in and repaired 3 weeks ago for the same frozen screen turns white problem + a loose power jack repair. When I received the laptop back they said the entire screen was replaced but I though I could sometimes see 1 or 2 black lines on the screen sometimes. However this really happened too rarely for me to care.

      I also use my computer for extended hours, sometimes up to 10 hours a day non stop. If it is relevant the day my problems cropped up, it was a particularly warm summer day (25 degrees celcius, i'm from UK)

      My laptop is an ASUS A43S with GT540M graphics card, and it has and i7 2430QM processor. My hard disk was replaced in January after a slew of BSOD problems, but that has not happened again. I have had power jack repairs twice, once last summer and once 3 weeks ago.

      I can find no satisfactory answer to my plight on the internet, and was hoping you might help me out!

      QJ my first thought would be that your graphics card is bad. It is hard to say though. I think you need to contact the manufacturer, especially if it is still under warranty.

      ud1093, the 1333/1600 Mhz is the RAM speed. The higher number will be faster.

      Thank you entreri, I've posted on a few support forums and you are the first one to give me a reply. However when I disabled my NVidia graphics card , the screen would freeze and turn white, does not mean something more sinister? Thank you!

    • profile image

      entreri28 3 years ago from Joplin, MO

      ud1093, you can get RAM with speeds over 1600mhz, but your motherboard must also support a given speed.

      QJ, many computers have built in video support as well. When you disable the video card the built in video controller will take over. Some computer actually switch back and forth based on how much power is needed.

      For programs that require more power, the video card will be used. For less graphics intense programs the built in video will be used. The built in video uses less power so it make your battery last longer by only using the more powerful video card when needed.

      So it may be your built in video controller that is malfunctioning. I would contact the manufacturer. They should be able to repair/replace whatever is needed.

I have a dell mini 10. It tends to get really hot and i know it only has 1 gig ram so it tends to go slow anyway.

(csmos i think) and replace it. Didn't stop the actions of start and stop. All fans are oporational. I hit the kill switch gently couple times and pc did full boot only to be greated with a blue screen message that said (overclocking failed) I don't know what this is as i don't know anything about overclocking nor did i try to attempt it. (writing was in (red) WARNING.. I manage to use pc but as soon as i shut it down or restart for any reason the same thing happens again. tries to boot then stops starts stops starts stops . How can i stop this i have 3gig of ram windows 7 with 55gig ssd nvd drivers all up to date.

      did complete clean . virus check with avast. clean out %temp%. full scan malwarebytes. SSD is about 2yrs old . PC has MSI . forgive me i am not computer literate hope i have given enough info for you .

      @spereira Your problem is hard to diagnose. If it gets excessively hot, that would be where I would start. Try to clean some dust out of it if you are comfortable doing that. If not, have it done professionally.

      @mona I think your computer may have been affected by a power surge or some other electrical problem. Try resetting the BIOS to factory default. You can google how to do it, include your computer model.

Doesn't show signs of over heating as well. I the ram and cpu and whatever else though the bios test run and it litteraly tested fine. I have 1 of my ram sticks ghetto rigged due to breaking the side plastic prongs but each time my computer will restart my computer would be static the entire time. I can run MMORPGS the entire time and then only after would it restart. I would run 10 programs at once (just various windows) and only after several hours would it restart. It typically interupts a long download a lot of times being a hit or miss. Theres no bells or whistles that go off when it restarts on me. I orignaly thought it might have been virus related which is why i formated my computer, no backup files at all. My battery was getting low i thought that might have messed with it took the battery out and just used adapter still shuts off. Used adapter for other laptop and still shuts off..

      Great article that sums up most memory problems. For those who reside in tropical countries, I'd like to add another overlooked problem to the list and that is moisture. If moisture collects on your RAM, it might prevent it from getting detected. A good way to solve this issue is to take out the memory module and rub the golden rim with a clean eraser (yep, the same eraser you use at schools). Then, replace the memory module into the slot and voila, you'll find that it works again.

      It is very odd that your computer only restarts during idle times. I would assume it is RAM, HDD or battery/power supply problem. It is good you have already checked the battery and RAM. Try to run CHKDSK to check for hard drive problems. You can do it just by pressing the windows key and "R" and then typing "chkdsk".

      Make sure your chipset drivers are all updated. It may be a problem with your computer going to sleep/waking up. You might try turning off all energy saving options and see if the problem still occurs.

      I have recently changed my motherboard & CPU with a Nvidia geforce 210 & a hard drive of 500 gb. Now I have 2 Hard drives & I am using both of them but installed Windows 7 in my new hard drive. After installing window it worked perfect but after 1 days when I started my PC, it stopped at Windows logo and not going ahead or any thing else. I restarted my pc but same thing again happened. Then someone told me that you should reinstall or repair the windows with the help of installation CD. I run a repair but same thing happened after one time use. Now question is that if this problem will remain in my system forever? Or there is any chance of solving of this problem. I do not have much knowledge of computer but I can do it with the help of Google. I am unable to find out the problem. May be as you said above, it can be a problem of RAM but please ensure me about this.

      I think you probably have a problem with the new video card drivers. You should start in safe mode and try reinstalling the drivers and/or updating them. Power on your computer and hold the F8 button to start safe mode. You will get a prompt and select Safe Mode with Networking so you can access the internet to get the new drivers.


      I would call Dell tech support. If it is still under warranty they will have you run through some steps to check if it is unfixable and will have yous end it in to be fixed. If it is not under warranty, take it to a local computer repair store.

      You're really awesome to be so responsive on this page. It's hard to find someone who knows a lot and is willing to take the time to share that knowledge too!

      So, here's my problem... I'm loathe to give up on the RAM I bought for my upgrade and am hoping you can spot the problem. Here's what I've done so far:

      I purchased a used PC that was described as functioning except for a bad PSU. The machine came with:

      Asus M4A78L-M Mobo (64 bit)

      2 GB (1 x 1) installed DDR2 RAM

      PowerColor ATI 5670 graphics card

      AMD Phenom II 955 black Quad Core CPU

      No HDD

      I replaced the failing PSU with a Corsair CX500M (500 Watts)

      I installed a Western Digital black caviar 1TB 7200 RPM HDD

      These two improvements had the system up and running (I'm writing you from the machine now). When playing Minecraft on 32 bit windows, it had some intermittent, jerky, stop-and-start type lag, but was playable.

      I decided that upgrading the RAM may help with this lag.

      I ordered generic RAM because DDR2 is so ridiculously expensive. I know generic is not ideal, but...

      The memory is 8GB (2X4GB) NEMIX RAM Memory DDR2 800MHz PC2-6400 Desktop DIMM 240 PIN - I checked with a Tom's Hardware geek (I mean geek in a good way) and the seller of the card. Both thought the RAM should run in this system.

      Mobo specs page (http://www.asus.com/Motherboards/M4A78LM/#specific... says the mobo can take the following:

      2 x DIMM, Max. 8 GB, DDR2 1200(O.C.)/1066*/800/667 ECC,Non-ECC,Un-buffered Memory

      Dual Channel memory architecture

      *DDR2 1200(O.C.)/1066 is supported by AM3/AM2+ CPU only. Refer to www.asus.com for the AM3/AM2+ CPU models.

      *Due to OS limitation, when installing total memory of 4GB capacity or more, Windows® 32-bit operation system may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is recommended.

      ** Refer to www.asus.com or user manual for Memory QVL (Qualify Vendor List)

      So, when installed, the computer would boot, but not post, no beeps, no bios, just blank screen.

      I tried the following trouble shooting measures:

      Flash update of BIOS to most recent version.

      Reset CMOS (which also resets BIOS to default) by removing and replacing coin battery.

      Tried each stick individually in each slot, also tried switching the slots while running both sticks.

      Upgraded to 64 bit Windows 7 instead of 32 bit, updated all drivers and ran all windows updates.

      Wash and repeat of trying each stick in each slot, etc.

      Tried running without graphics card.

      Visually compared the card configuration against FBDimm to be sure it is the right type of card.

      The card was made in US by Texas Instruments.

      So, with a heavy heart, I reinstalled the original 1x1 RAM, which has the system running again.

      So, I'm sure the board is fine and the slots are fine. What I don't understand, even with generic, is how both new sticks of memory (not used or refurbished) could fail. Wouldn't just one or the other fail when you have a matched pair like this and try them individually in each slot? I understand that new memory failures are rare, so both failing seems twice as rare.

      Another confusion comes from looking at the Qualified Vendors List for memory from Asus. The machine is supposed to take up to 8GB, but the list only shows up to 4096MB(Kit of 2). Is that saying 2 sticks of 4GB or 2 sticks of 2GB to make 4GB? Just want to be sure there isn't something I'm missing as far as how much RAM the machine can handle.

      So... I very much appreciate you taking the time to try to help me out of my pickle. I can return the generic ram, but I'd rather get it running, Also, I really don't want to go spend $250 on QVL ram and have that fail on me too. Thanks so much!

      It seems you have tried many different ways to fix the problem. I don't really know what else to recommend you try. The RAM may or may not be faulty. Sometimes even RAM that is supposed to be compatible does not work. I would try to return it and try different RAM honestly.

      i have a strange problem for years, totally changed 3 hard disks,, but the problem is not in hard disk. i start my computer and work with chrome mostly, within 15 minutes my computer will turnoff, (not shutting down or restart) it shows no signal in monitor but the cpu will run even after that. I have to use restart button to work on it again. My first hdd. it corrupted after several turnoff. i dono anything abt pc at that times, service center man just told there my hdd is corrupted and that's the problem. I believed that. and bought my 2nd hdd. Again several turnoff occurred. My 2nd hdd shows error msg indicating there is a problem with hard disk of this computer. finally it also failed. i contacted a different service man, he said ram slots are not good and that's causes the problem and we paid 1200 for him, He confirmed me there is no heat problem and mother board is just fine and he even assures me that there will be no problme anymore. So i bought a new 3rd hdd. The problem started within 1 day itself. again system getting turnedofff showing no signal msg in monitor.. The 3rd hdd is running for past 3 months, till now there may be approximately more than 30 turnoff occurred. An now i am in fear that this would also may get corrupted soon. One more strange thing is if i opened mozilla no problem occurs, but i only use chrome, the problem will also occur if i open microsoft preloaded chess game. I don't know what exactly going on my pc. Can anyone help me??

      Try to shut down any programs you are not using. Programs running in the background still take up RAM. It would probably be best to buy more RAM. Even if the game recommends 1GB it would probably run slow if that is all that is available.

      Make sure you run your anti-malware scans to make sure you do not have programs running you do not know about.

      Hi there I recently encountered a problem. My computer started freezing them blue screened I restarted the computer and it wouldn't get to windows. I thought it may be a ram problem. I took the ram out of the 2nd slot and it booted no blue screen I also cleaned the registry as it had conflicts. So I assumed it was the 2nd slot was bad. All seemed well and then the next day it started freezing again. Any suggestions.

      I have 2x4gb ddr3 ram.

      Oc. 3.8ghz athlon ii x4 with uprated cooling. Cleaned on a regular basis I mean weekly I haven't checked the ram slot for dust yet though.

      Tim Anthony 3 years ago

      @adam You do not need to clean your computer once every week. It's a good habit to take care of your system so nicely. Once a couple of weeks shall do just fine.

      About the BSOD (Blue Screen Of Death), I suspect it is just a RAM slot issue. I recommend you to inspect recently installed/uninstalled software that may concern the system files. You mentioned that there was some kind of conflict with the registry, hence I recommended you so. Please tell me which operating system you have? Windows 7 or Windows 8 or Windows 8.1, and the operating system version please.

      Ok let me get your advice on this. I had a computer at work I was using to program Plc. My boss's son got on the computer's and invited a rather nasty virus in which crashed all the computers in the office in one day. Since then the teck came in and cleaned house. My boss asked if I could build a computer to use for myself rather then buying one. Knowing a "little" bit and being and idiot I said I would try. I build the computer and pulled what data I could off the old hard drive. "It had files on it worth far more then ten computers" it worked fine for 2 month then the "blue screen of death" which was how the old computers started dying. So my first guess was" virus" it must have been brought over with the data. No problem I have made paper copy of the programs by now. So while it is painful I could retypt the programs back in. I then reformate hard drive and reinstall os "windows 7 home " . It then works for 2 weeks then bsod. Ok I googled the problem and read that in some cases it can live through a format and still be on the hard drive. Ok so I pull hard drive out and replace it with a brand new one. Again 2 weeks and bsod. So more googling .I call motherboard manufacturer they say to update bios I try that still 2 weeks in bsod. Ok by this time I am mad. time to pull out the big guns . I Pull out the credit card. New mother board new hard drive new power supply.Install all this and again 2 weeks later bsod. I didn't get new ram I used the old one from the computer that I just build. Not from the computer that had the virus . I talked to a guy he says" you probably just had bad ram and it just looked like a virus was transferred " so ok I put new ram in it and again bsod 2 weeks later. I ask him again. He said well some times when you have had bad ram it can corrupt the virtual ram and just replacing the ram won't do it. You need to reset the virtual ram as well . That is we're I am now. O I also upgraded to windows 7 professional durring all this. What do you think?

Now I press the On button but it will not boot up, I can hear the fan spinning and the HDD attempting to start but no booting up at all, I should mention I noticed the new HDD does not have a 4 pin block in next to the SATA data and power connectors. any advice will be very much appreciated.

I have two 8Gbyte ram memories. Windows Memory Test said one of my memory is bad. I took out one, same problem, switched it with the other same problem, put the second in the other slot, same problem, put the first one back in the same slot as the second and still same problem. Can it be that, both of my memories or both of my memory slots are faulty?

      the same things happened to my PC. i added a new RAM in the second plot. At first, it worked smoothly but after a week it my PC showed the above symptoms. From no.1 to no.5 everything happened the same. I took my PC to a local shop but without the new RAM. They repaired it in few hours. thenafter I inserted the new RAM again and it showed the same symptoms. So, i immediately removed it. Now, can't I use that RAM nomore? Is it totally damaged? Need help!! Please!!

      Thank you for writing such a detailed article explaining many different things, its obvious that you not just know these things but understand them, and as a technician in an unrelated field the difference in knowing something and understanding something is night and day

      My Asus notebook freezes on the desktop after it boots up. Sometimes it says battery not detected. I can do nothing on this computer. tonight I found that after I left it on for almost an hour I can finally use it. Please help.
