First off, I am not very computer savvy, so please keep it as simple as possible...Thanks! Okay, about two weeks ago, my power supply went out, so I bought a Dynex 400w replacement and had it installed. Turned the pc on, but never explored any further than that. About a week ago, I tried logging into WoW and after about two minutes of play, my pc completely died, no warning, no error message, nothing. So I tried another game (The Sims 3), same result, but after ten minutes instead. When I stream music/videos, no problems, and playing browser games don't seem to affect it either. I have updated the drivers for my card (nvidia GeForce 7600 GT) and downloaded a program to watch the temps. The temps never went above the max or below the min. I have heard that sometimes when a power supply goes out, it can take other hardware with it. Someone help! lol Thanks so much!
