PC is losing power....?? any ideas?

Starting yesterday, or at least I first noticed it then, my PC just lost power and then restarted itself out of the blue.... I had just downloaded Torchlight and was starting up a game and the PC just died... I thought the power had gone out in the apartment... but today, it happened again, while watching a video on Gametrailers.com.

Now a month ago I upgraded my PSU & vid card... maybe my PSU is faulty? or maybe the PC is shorting out because my GPU just barely fits in the case and the end of it is actually touching the case (where the HDD's are mounted).... but if it was because of this, you'd think it would have been doing it since I installed the hardware, right?

Anyone got any ideas? thx in advance.

stop tripping over the power cordrock_solid

ahh... picking my feet up when I walk.... I'll try that.

Is your old PSU capable of powering your new parts? You might try it... Could be a faulty PSU, I hate problems like this, fortunetly I haven't had one for a long time :) But random cold reboots are often a sign of PSU trouble.Captain__Tripps

I'm running a GTX 275 w/ a 600W PSU... i'm pretty sure thats enough... however, I just spent the last 2 hours swapping PSU's in and out of PC's..... (had an extra 600 PSU) and my PC still wouldnt boot after the swap.... I hit the power button multiple times and BAM! away it went..... so I'm not sure whats going on.... I'm led to believe that my Power Button is faulty, bad wire maybe.... but... that wouldnt cause the system to just SHUT DOWN and restart..... maybe my system is grounding out somewhere?

I generally don't tie off unused wires from the PSU.... I just stick them somewhere where they shouldnt move and arent touching anything. I'm so lazy.

Try checking your temperatures.
