paulktreg Posted November 28, 2011 Posted November 28, 2011 There is a temperature sensor inside the power supply, usually connected to the heatsink were the switching transistors are mounted for the +12V rail, that shuts the power supply down when a set temperature is reached.

So when the PSU shuts down...the entire computer goes with it, yeah?. Edited November 28, 2011 by NuComer Share this post Link to post Share on other sites More sharing options...
Waco Posted November 28, 2011 Posted November 28, 2011 So when the PSU shuts down...the entire computer goes with it, yeah?. Yes, but based on your signature, there's no way you're overheating your PSU. Share this post Link to post Share on other sites More sharing options...
NuComer Posted November 28, 2011 Posted November 28, 2011 Yes, but based on your signature, there's no way you're overheating your PSU. I'm actually using an HD4870 instead of the 8800gt. The thing is, if I underclock the 4870 to 700MHZ core /835Mhz mem I can use it no problem, if I use stock speeds I can play for like 2-8 mins and the my screen goes white and it gives me an 0x0000000116/117. Any Ideas? Share this post Link to post Share on other sites More sharing options...
Waco Posted November 28, 2011 Posted November 28, 2011 Sounds like you need to take a closer look at your video card. Clean it out or something... Share this post Link to post Share on other sites More sharing options...
NuComer Posted November 28, 2011 Posted November 28, 2011 Sounds like you need to take a closer look at your video card. Clean it out or something... Yeah, I did that already, replaced the TIM and even took the heatsink on the VRMs apart and was greeted with one of the weirdest things, it had like a tiny drop of some sort of liquid on the thermal pad, and the thermal pad was rather...hard instead of soft and mushy. Any ideas on the symptons of overheating VRMs?, the only thing I've been able to find is that it can in fact turn your video card off, which could explain my situation.

Waco Posted November 28, 2011 Posted November 28, 2011 Did you replace the thermal pads on the VRMs? Share this post Link to post Share on other sites More sharing options...
NuComer Posted November 28, 2011 Posted November 28, 2011 Did you replace the thermal pads on the VRMs? I didn't, they are actually in great shape but I can't tell if they're good quality or not. Btw, thanks for all the help man, appreciate it. Share this post Link to post Share on other sites More sharing options...
Waco Posted November 28, 2011 Posted November 28, 2011 If they've hardened it's possible they should be replaced. Since it runs fine at slower speeds it certainly sounds like a heat issue. Can you point a fan at the card to see if it will run longer at stock speeds? Share this post Link to post Share on other sites More sharing options...

About the fan, sure thing, I'll try that when I go home for lunch in about 3 hours and let you know. Thank you again!. Share this post Link to post Share on other sites More sharing options...

Tried the fan and it worked great on stock clocks!, now I have another question, how would I know if its the video card overheating or the PSU?
