Ill try and make short and sweet.
I have a PC that I built a couple years ago and has been a great computer for gaming, photo editing, etc. The other day, I came home and computer was just off. I rarely ever power it down and typically just on all the time.
So I messed around and nothing I could do would get it to power on. Took out power supply and went up to local Frys and they tested it, confirmed power supply was dead. Well they didnt have another one like what I needed. Mine is a 500w and the fan blows out the back, not the top/bottom. And my CPU/motherboard plug, only has 4 pin holes and not 6 or 8 or whatever all theirs had. So I bought one, didnt work, returned and got another one they had. This one seemed to be ok, but only problem is...
its 400w and not 500w like my old one
has an 8 pin CPU/motherboard plug, so i plugged in just half of it into the motherboard. seemed to be ok
so yay, now computer has power. it boots up... gets to screen where i choose my profile, and window starts up... gets all the way to my desktop and its there for a few seconds and boom.... blue screen and then loops back and restarts. does this over and over. I tried doing safe mode, system restore, etc and still same thing always happens.
this power supply was cheap. Like $15 cheap. and its very lightweight. almost too light. and of course, it was only 400w and not 500w.
Do you think Im getting the blue screen because of this power supply? by finding and replacing with the same original 500w, would work fine? or do you think when original power supply went out, something damaged my hard drive too?
