CPU or RAM issue?

Whenever I'm playing Counter Strike, or watching a flash video, if my computer has been on for at least 10-30 minutes (different every time), I get random drops in FPS, in counter strike it will drop from 60-80 to 5-18 and in a video it will drop from the normal rate to 1-3.

Since this has started happening I have replaced every part of my computer except the CPU and RAM, I've reinstalled windows several times, quad-checked all my drivers and software is up to date so the issue is 100% within one of those 2. I can't figure out which one though, the thing is, my computer fell a while back.

AMD Phenom II X6 2.8 Ghz

Corsair Vengeance 2 X 4 Gb DDR3

Sapphire HD 7750 2 Gb

Samsung SSD, no other hard drive

600W Gaming PSU

Update:

The motherboard including everything else is brand new.

  • take a look at the cooling fan in cpu, check your system temperture,if the temperture work well,then check the ram,test single ram in your system.in my opinion,mybe one of your ram not work well.

  • Hi,

    Combine all the thumbs-up'ed answers below and then take a look at the Mfr website for Your motherboard ... You may also have a "bottleneck" between the 2Gb graphics card and the system's "bus architecture" that may not either support a GPU-RAM amount over say 1Gb, or it may be using a RAM speed too fast for the mainboards system bus speed between the video connectors/devices.

    This would also be a situational type of thing if Your particular motherbioard uses a different version of "PCI-bus standards" than Your video card does ... in other words : Your video card uses the latest V2.5 PCIe standards (and multiplier rates), but the motherboard only supports an older PCIe 1.9 standard (and multiplier rates) ... so the card "steps down" to use the older standards during especially intense or overheating moments.

    G'Luck!!

  • Almost everytime I start playing this friggin game on FB it seems to freeze up on me for a few minutes but eventually it recovers and I can continue.

    Its because my computer starts another program. A scan - or it wants to install Java - or some damn crap like that. Apparently my computer can't handle all those tasks at one time.

    I'd check to see how many programs are running at one time? Almost everything you have on your computer will have a start up prompt and is running in the background. Shut off all the programs that you aren't using.

    Go to START and in the box type MSCONFIG (you prolly already know how to do this) and then go to the startup tab. Take the check marks out of everything you recognise. If you don't know what it is - leave it alone. Then restart your computer.

  • As a suggestion and not an "answer" you could go into your BIOS and disable any power saving features that may be toggled on. Sometimes the systemboard and power supply in the newer units don't play nice when it comes to Power Management even though they're designed to. Also, check for over-heating.

    Also, if you have a friend with a PC, see if they'll let you swap your RAM with theirs for a bit, to eliminate that variable.

  • Simple it could be the overheating of your cpu be sure that u are in a best ventilated room and check the cpu temperature if it not working go for any other heatsink that is any other high capacity cooling Fan

  • When you said you replaced everything, did you replace your heat sink? Chances are you're PC is over heating. Replacing your CPU wont change this. If over heating is the problem you will need to replace the heat sink.

  • get a RAM checking diagnostic routine on a boot disk and run it. Also, if your motherboard has ever over-heated you may need to just get a new computer.
