Computer crashes on first boot, then laggy afterwards

I've been trying to fix a very unusual and frustrating problem for the past few months. For some reason, my computer will crash about 10-15 minutes after its first boot (however, ONLY while I'm playing an online game). I'm forced to give my computer a hard reboot in order to get it running again...and then it will run fine (but fairly laggy) while playing the same game...

What's even more unusual is that before my computer crashes on its first boot, it runs PERFECTLY: I'm getting 40+ FPS in online games, etc. However, when I reboot it after the computer crashes, my games will run but very poorly for my specs (10-20 fps) EVEN on lowest graphics settings. Furthermore, my games are not very graphics intensive: Everquest 2, Skyrim, GTA4, etc should run decent on my specs.

I am really desperate for a solution...I've tried installing graphics drivers (this actually made it worse, had to go back to my old version) cleaning out my system, running virus scans, etc to no avail....

Here are my specs:

Motherboard: Gigabyte GA-880GM-UD2H Rev 1.0 (BIOS version is F4)
CPU: AMD Phenom II X4 925 (AM3 socket)
Memory: 4GB 1333MHz DDR3 Corsair (2 sticks)
Graphics Card: 1GB XFX ATI Radeon HD 6870
PSU: Antec EarthWatts 650W (38A on the 12V rails)

PLEASE HELP!

  1. Are you overclocking?
  2. I am not overclocking.

    Hm. That's a little strange. Could it e a heat problem? you can try to monitor temps with hwmonitor. Also, it could be a RAM problem. RAM is one of those things that will fail and cause all sorts of silly. You can test the ram with memtest86+, or a similar program.
  4. Thank you for your quick responses!

    I will try out those two tests and post observations in a bit...
  5. I went ahead and downloaded HWmonitor to check my temps. Everything seemed reasonable except my CPU temperature....each core was fluctuating between 65-75 degrees Celsius! :0 These temps were also registering while I was just browsing the internet. Furthermore, I could really feel the heat from some of the hardware after opening up my computer: For example, my RAM sticks are positioned right next to the CPU's heatsink, and they felt very hot.

    What could be causing the heat? I recorded these temps just 15 or so minutes after turning on the computer... (did not play graphics intensive games).

    I also ran a Windows Memory Diagnostic test but it came back saying there were no problems detected...so I'm fairly sure it's a heat issue (like you said in your post) now...

    Well, first of all, I would clean out any dust in your case, and in your heatsink. This is a bit tedious, but it may solve the temperature problem.
  7. Should I also reapply thermal paste on the CPU? I haven't put any extra in over 2+ years so it could have dried out?
  8. Ok, so I finally found some time to clean out my CPU's fan/heatsink. I also reapplied some thermal paste (arctic silver 5) for extra fortification...

    Well, I started up my comp to check temps, and noticed that the CPU was averaging 45-48 while I was simply browsing the internet/watching youtube videos. Before I cleaned/put on thermal paste, my CPU fluctuated between 55-65 degrees while I was on the internet...so quite a noticeable difference. However, is mid-high 40s normal for simply going on the internet? I haven't tested the chip's temp while playing games...so I'll get that info asap as well...

    Those are a tiny bit high, but more than acceptable. You could also move your computer to an area with better airflow, such as on a desk, so it has ample room to breath.
  10. Went ahead and move the system around as well. So far, I haven't experienced any crashes! Hopefully my problem is fixed now :)

    Thank you for all your help, explOitfinder!
