Hello All,
I have a computer that I put together in January, and has been running great. For various circumstances my brother is getting rid of his computer and let me have his more powerful GPU. I installed it, and downloaded drivers for it yesterday and it was running fine. This morning I get up and start playing a game on it, and after about 5 -10 minutes, my computer shuts off like there was a power outage and won't start back up or respond in any way to the on button. I took the new video card out and put my old one back in and it still won't start. The quick search I did on this makes me thing its a power supply issue, but I don't understand why it won't turn back on with its old set-up.
The hardware is all relatively new, so it's hard for me to imagine that they've gone bad yet.
my power supply is an ATX-CW420W
the old GPU is an AMD Radeon HD 5450
the new GPU is an AMD Radeon HD 6870
