The short version is that I boot my PC up in the evenings (it's off all day) and sometimes while playing games things will start to slow down and sometimes turn off completely. However a reboot always seemed to bring everything back and working once more.
It always seemed like a reboot fixed the issue. (So I figured it was a Windows problem). However over the past two weeks or so the time I've been able to use my desktop between "random shutdowns" has decreased, now I can't even get it to stay on for 60 seconds. I thought it might be overheating so I grabbed a can of air and went to town on it, no luck.
Another thing I've noticed is that my fans seem to stop spinning (or they start and then stop), I figured they were clogged up but now I'm not so sure that's the problem.
Nope, can't get that far. I've had it off for a while now but still about a minute after boot it just shuts down. I've checked the temperatures in the BIOS and although they are a bit high I recalling checking my temperatures a while ago (other unrelated problem) and the readings now are about the same as they were before.
