So, I've been having a ton of problems with my machine lately. Starting with my RAM incident solved here, a crashed Hard Drive, and now an overheating video card.

So This past week, I've been noticing that my computer seems to crash and restart at random intervals. No viruses or anything, but today I booted up some Painkiller, and the game crashed about a minute into the intro. I decided to run OCCT to see what was up. Turns out the card is FREAKING HOT at about 75+*C idle, and 92*C on a full load. Dangerously high levels, obviously.

I want to know if this could have been caused by my fallen RAM (see link above) shorting out something on the card. The good news is, I was planning on getting a 260 this month anyway, but I still want to know. Or are all of these symptoms caused by something underlying I'm not seeing?

Thanks!

It's a Raidmax Volcano. Got it in 2007. It wasn't dirt cheap, but rather cheap. I think I paid $60 it, with rebates. I honestly did very little research into the power supply, it was kind of an impulse purchase.
