PC turns OFF by itself

Hey all,
I have a WC setup so I don't think it is over heating, since speedfan says my cpu is -64C although my GPU is running a bit hot.

I fell asleep last night watching a movie I have already had on my pc for the better part of a year and watched many times, When I awoke I did my normal routine of turning the pc on so my girlfriend could use while I am at work since I have truecrypt on there with a 37 character password. I noticed it was off and just assumed she turned it off the night prior.

When turning the pc on I got to enter my password and it was getting ready to load windows and then a message popped up saying a windows file was corrupt and I idiotically hit a key to get to the BIOs to try to fix it and it instantly powered off the pc.

So i didn't have a chance at writing down the file path to see which file it was that is corrupt. I attempted to log to the pc after that and nothing happened, so i rushed off to work.

Went home for lunch and turned the pc on and like magic it booted up I thought i had won so went to gloat to my girlfriend and when walked into the room it was off, tried a few more times and it would get past the windows boot up and like after a few minutes just shut off.

I was thinking maybe it is a power flickering issue like a surge of some sort. Any help would be great on fixing this since I am having the worst luck with computers.

Thanks in advance

Skynet, its starting...

But nah lol, Sounds like windows is just corrupted and needs a windows repair. When you say dont boot, meaning, can't see BIOS screen? Or dont boot meaning it wont just load windows?
yes 2 Hard drives in Raid and it does boot just shortly after windows loads fully and ready to go it just shuts down
similar thing happened to me and it was the power supply...
was wondering if i am just getting some sort of surge and it is making it shut off.

guess when i get home i will try to run slax to see if it is a software or hardware problem
its either the PSU or the HDD's, guarenteed, use a HDD health program to see what they are like, if they are good try running on just one 8800GTX to see if the lowered power demand helps the PSU
one of the 8800's fried a week ago so have been just running one and everything was fine until now, suggest any hdd health programs?

I have a WC setup so I don't think it is over heating, since speedfan says my cpu is -64C

Speedfan is wrong. There is no way you are -64C on a water cooled setup. Either you meant 64C, you live in a -65C degree climate or it's just plain wrong.

Check your CPU temps with something else. Also, what is your GPU @?

Then check:
PSU > Memory > HDD

I had the same problem as you, and my problem was defective RAM. So check that out too if you haven't.
ok thanks, well work is over will try to go home and figure this out...
might be ram to since i recently added 2 more sticks
Ya might be a bad stick. Also, like I said a few back, check your cpu temp cause it's not -64C. If you are idling at 64C, it might be thermal shutdown on load.
I'm 80% it's your memory.
Try using only 2GB or try different sticks at a lower frequency.

I agree, I had the same kind of failure and it was the PSU

You could also try and look for a loose connection (worth a shot)

Well turned it on and ran slax to start deciding which piece of hardware is messed up and as soon as i took off the side i noticed i am not getting any water flow... guessing my pump is dead which is just great since i had to fix it recently for leaks since the sides cracked.

guess i need to take it apart and see if i can fix that and see if everything else works after that... hope i didn't over heat everything
