Windows 7: new hardware problems

new hardware problems

here's the run down of what i have done:

i built the computer (sig) and installed windows 7 64, adjusted the ram timings to set my RAM to their correct speeds and everything was running fine (in games and web browsing) for a couple of days.

I then gently overclocked my video card and cpu and tried to play a game online and got a Grey Screen of Death associated with ATI 5xxx cards. I clocked everything back down to stock speeds and the problem persisted (where games ONLINE would crash within 10 minutes of playing). I looked in my case and noticed that the 4 pin part of the 20+4 pin connector from my PSU had fallen out of the motherboard. I plugged it back in and also changed my RAM timings back to auto in the bios. The grey screen went away entirely and I was able to play games for extended periods online again.

I thought my problems were over but I ran multiple stress tests including prime95 for 16 hours, memtest86 for 8 hours, furmark GPU for 4 hours and was unable to cause any instability. I felt very confident that the problems were fixed but I entered an online game (world at war) and left it in spectator mode in a heavily populated server and went AFK. When i returned the computer had rebooted due to a BSOD error referencing 0x0000009C: MACHINE_CHECK_EXCEPTION.

I ran all the stress tests again and couldn't replicate the error so i wrote it off as a fluke. I was crash free for 2 days but i was not comfortable so I ran the far cry 2 benchmark on loop overnight and it crashed after an hour to the desktop with no errors noted. The next day i uninstalled and cleaned off the 10.3 catalyst drivers and installed the 10.3b catalyst drivers, ran furmark for an hour and ran Far Cry 2 benchmark for 2 hours with no crash. Believing the issue was finally resolved, I left another test of Far Cry 2 benchmark on loop overnight.

I woke up this morning with a BSOD that happened 20 minutes after I started the benchmark, it was the 0x124 code i posted above.

I turned off speedstep in my bios and ran the far cry 2 test again and received the same 0x124 error code.

it is so aggravating because it passes memtest86 and prime95 flawlessly, it has never crashed outside of a 3d game, but I cannot find the culprit. any and all advice is sincerely appreciated, this has been a NIGHTMARE.

I've passed Memtest86 many times, only to discover that my memory modules needed cleaning up, and reseated. Use a pencil eraser to clean up the gold plated connectors on the modules, and reseat. Also inspect the DIMM sockets, and vacuum out if need be. Many times interminent BSOD's can be traced back to dirty, or not properly seated memory modules. The DIMM connectors expand, and contract with heat. Over time, they can unseat themselves slightly. Hope this helps.
