Sorry to bump this, but I finally got around to troubleshooting a bunch of stuff, and unfortunately have yet to find a solution. I'm not sure if the problem has gotten worse, but it has gotten increasingly obvious. Crysis and the newest EVE patch both lock up and force a restart within minutes of starting them.
I found that my video card is, in fact, sharing an IRQ address... with a firewire port that I never use. Doubtful that this is causing anything.
I ran the Windows Memory Diagnostic tool, and it didn't turn up any problems.
Which leaves overheating. I wouldn't be surprised at all if this is the case, but I've done some extensive work and I haven't managed to fix anything. For reference,
this is pretty much my case, the specs there are identical except for the fact that mine has an AMD AM2 socket instead of the Intel.
I messed around a bit and I realized that
all of the fans were blowing air out. For starters, I switched a couple of them around. I also used some of that plastic that toys are always impossibly difficult to get out of to redirect air flow, as my video card is freaking huge and messed up what seemed to be the intended flow of the case. I also went into the BIOS and told the fans to work harder more often. Finally, I cleaned out any and all dust I could find with a can of compressed air. I live in an old house with bad ventilation, so the stuff accumulates quickly and can really cause adverse effects if you let it. Still, if I go into the BIOS after something bad happens, I find that my CPU is running at a good 54° C. Not good.
Unfortunately, I also cannot continuously monitor the temperature of my computer, at least to my knowledge. MBM is not compatible with my motherboard.
Anyone have any bright ideas as to how I could improve this?
