I've had my computer for about 2 years and about six months ago it started rebooting every time I would play a game, hence why I haven't played a game since then . What happens is that whenever I play a game, the computer will shut off anywhere from 5 to 10 minutes after I start playing and trying to restart will result in it shutting off before I get to the login screen for the next 4 to 5 minutes. Another weird thing is that even if I only play a game for just a minute and then shut down the game, the computer will automatically shut off before the game exits out to Windows.
I have thoroughly cleaned the dust out from the computer (with the exception of the cpu cooler, as I would have to reseat the CPU and I don't have thermal paste on hand. Here is a copy of my temperatures after playing a game for about 5 minutes:
Hardware monitor ACPI
Temperature 0 40°C (103°F) [0xC3C] (THRM)
Hardware monitor ATI Radeon HD 3850
Temperature 0 67°C (152°F) (GPU Core)
Hardware monitor ST3250410AS
Temperature 0 40°C (103°F) [0x28] (Assembly)
Temperature 2 40°C (103°F) [0x28] (Air Flow)
I've used memtest86 and seagate tools so I know the ram and HD are fine. I've also used a PSU tester and it came back fine so I don't think it is the PSU. I'm thinking it might be that the video card is dying, does anyone have any other suggestions of things I can do to try and narrow down the problem?
It sounds like you've narrowed it down good. I'd try to stress each component (Furmark for GPU, P95 for CPU) individually and see if you can pinpoint which one is causing it. Keep an eye on those GPU temps though, furmark seems to blast GPU's.
I think your CPU is overheating. Some motherboards have a setting in the bios that will shut the CPU when it reaches a certain temp. You said you did not clean dust from the cpu cooler, and those temps seem high. Just curious, why didn't you clean the cpu cooler? You should be able to take compressed air that you buy in a can and blow it out.
I did use a can of compressed air to blow out the cooler. What I meant is that I didn't take the cooler all the way off and clean it out and then reattach it because I don't have any thermal paste on hand. I think I am going to order some thermal paste and try cleaning out the cooler for the CPU and reseating the heat sink to see if that has any effect.
I've actually used a couple of different monitoring programs and they all give CPU temps around the same values so I think the 64 C is probably accurate.
Well that's one entire fan more than mine and one of them is bigger than mine.
I'm not sure why it would be that high. Unless whatever you're using is giving you wrong temps. The AMD overdrive program will be accurate. UnQuote
Not being funny Dmitry, But after I used Acc to unlock my core, Amd O/D says my temps are -256 on all four cores, I have also read a lot of other similar posts to that effect so Maybe trying several temp progs is a reasonable idea?
