Shutting down every hour

Shutting down every hour
I'm really pulling my hair out...but pretty much like the title says every hour after I start computer it locks up. There are only 2 things I can attribute this to...the computer has been running flawless since I built it last fall.
A. I installed new AMD drivers for video cards Catalyst 12.8. I see no other people complaining about this problem however.
B. Left computer on one morning by the time I came home there was a thunder storm going on and my computer was black screened.

These 2 events happened close to each other can't think of anything else that has happened different to my pc.

I have removed catalyst and reverted back to old divers did not work. My windows is on C: an SSD drive. Everything else is on E: I have wiped my C drive and reinstalled windows. This does not work either. Have run several anti virus programs, anti malware etc...

mb is not over heating nor are video cards.

Every hour, I'm to the point where I just reboot to avoid the crash. Any ideas?

thank you.

RE: Shutting down every hour
Are games running as good as before?
PSU may be the culprit.

Yes, everything runs perfect till it locks up. Will have to look up manufacturer of PSU and check that out. Do you think it would actually fail literally every hour?

RE: Shutting down every hour
The last PSU that died on me failed every 10 minutes. When I changed it for a new one, evertyhing "went back to normal".

A thunderstorm + running PSU = quite a dead giveaway that the PSU protected your hardware at the expense of itself.

If you can borrow an equal PSU you can test it out. If your PSU has protection modes (undervoltage, overvoltage, under current, short circuit protection, etc..) it could be just the PSU and not the hardware. I'm pretty sure that the shutting down is due to a faulty PSU. Since there's no more power. A dead ram module or hd don't create something drastic as a shutdown.

If the PSU is retail bought, you could still have a valid warranty. Full refund or a new PSU! What's not to like?!

Ouch... Like everyone else said, likely the PSU. Until you get a new one its not recommended that you use your computer Big Grin. Did you have your computer under a surge protector? that is just as important as a good power supply.

Cheers

Shutting down every hour
I had bad RAM sticks do something similar. I would say it is the PSU or RAM. In my case, I replaced the PSU first and the problem was not solved. I then tested the RAM and found 3/4 bad so I replaced all 4 and the problem was corrected.

Actually its locking up....nothing is responsive as you click on windows etc...followed by black screen. I have to power down completely afterwards and restart computer.

*UPDATE*

I have cannibalized PSU from another PC and hooked it all up....1 hour later same thing....locked up/unresponsive. PSU can be ruled out.

While I have PC open I'll try removing RAM modules one at a time test out that theory.

This situation is just unreal. Appreciate those of you helping me.

good that clears that up, usually if its a psu you'll get power downs or restarts and sometimes tripped overprotection as well as the screen freezing with bsod's.

i would test the ram like mentioned above. if that tests good i would start up in safe mode see if it stays up, then i would prolly go into msconfig and temporarily disable startup and services. a lot of freezing problems happen when a piece of services software is loaded and is corrupt.

ive also had defective or too high overclocked gpu do the same thing except usually you'll see screen tearing, etc along with it.

good luck
