Hello everybody. My pc shut down while i was playing and wont turn back on now. I mean, pressing the power button wont do anything at all. I'm thinking its most likely my power supply unit but I would like to know is if there's a chance theres something else. I think my motherboard could be the reason too. It was running on high temperatures when this happened, so it was not unexpected, not THAT high though. Im probably getting a new PSU tommorrow, im just wondering whether there could be something more broken in there.

So what im actually asking is, could the PSU have possibly acted as a safety resistance (or something) and burnt itself to save the system or is there a possibility the damage has gotten through and damaged more components? Just asking so that I know to save extra money just in case ill have to buy more stuff to replace in there. On that note, it's not the wall socket, neither the case power button thats faulty- just so we rule some shit out.

This happened sometime ago, and ive been using another unit ever since, just want to fix that one too. I aint got it in front of me atm, but ill try to recall the specs:

4GB ddr3 ram of some kind(couldnt have been something cheap)
amd fx6 gen (can recall exact model)
650W psu (corsair if i remember right)
6850HD gpu
a coupla of HDDs
and some random mid tower case

I think my gpu or cpu, (cant remember for sure) was running on around 80-90 Celsius Degrees when that happened. Could be wrong though, but thats how i remember it.

I know I havent given enough stuff for anybody to actually KNOW what has happened, just asking for any ideas, anything at all.

EDIT: Woah i forgot to mention the motherboard. It was a sapphire unit, 7hundreds-something gen.

So I just got the new PSU, hooked it up, and the pc still wont turn on. Nothing's different, no feedback at all. I press the button, nothing happens. Perhaps the power button could indeed be broken? I dont know. What would cause such an issue, provided that the PSU is brand new and working? Any ideas?

Furthermore, is there a process I could go through to start eliminating probable causes? Like, test each component on its own to find the malfunctioning one(s).

I just did this [http://www.youtube.com/watch?v=G4FOBL1c3pA], dont know if its legit, but my system didnt turn on. So im guessin the power switch has nothing to do with this and its more likely my motherboard?
