I've been dealing with an annoying freezing/BSOD problem with my PC for the past few months and I think I've narrowed it down to a voltage problem. (PC freezes minutes into a game. In the past it would sometimes do it on videos and even just surfing the internet. After a freeze/reset the system would sometimes lock up during POST). I've done everything from replacing the PSU, reinstalling Windows, reapplying thermal paste to CPU, and the problem still comes up. The PC has definitely been running better after replacing the PSU, as with the old one it got to a point where it would only stay on for a few minutes on desktop before freezing/BSODing. Now it runs fine with everything except for gaming.
Also oddly the problem has occurred in the past and disappeared for months, only to resurface again. I want to solve this once and for all.
Do you think this is a voltage issue? RAM is 2GB (x2) DDR3 9-9-9-24 and set to auto.
AMD Phenom II Quad Core 945 3.00Ghz
GPU: GTX 460
PSU: Corsair 750w
Motherboard: M4A87TD Asus
Windows Vista Business 32bit
I haven't as I'd have to buy a new one to do that. And going by typical dying GPU symptoms, my problem doesn't really point to that as the issue. Whenever the PC freezes it's always a straight lock or BSOD. No screen tearing/flickering/weird colors or anything of that sort. GPU temps are stable as well.
You wrote "(PC freezes minutes into a game. In the past it would sometimes do it on videos and even just surfing the internet. After a freeze/reset the system would sometimes lock up during POST)." That's what happened to one of my systems when I had a bad GPU; i.e., it would lock up and it required a hard reset. Replacing the GPU resolved the issue.
Edit: Have you run Furmark or a similar GPU stress test?
Ran the test with one stick and it ran for 4 hours with 0 errors. Then ran the test on the other stick and the system froze within a minute. Still have to test the next 3 DIMM slots but it looks like I've found the problem.
