I've been running this computer for about 15mnths now with no stability issues at all... up until yesterday at least. Now I'm getting corrupted files on occasion and the system periodically reboots every 10-15min with no apparent cause.

Normally I'd expect it to be the PSU if the system is randomly rebooting, but the reboots will often happen when the system is just sitting at the desktop doing nothing yet run perfectly fine when heavily loaded, and removing hardware to lessen the load on the PSU doesn't seem to do anything to lessen the frequency of the reboots.
It does however consistently reboot whenever I download any Windows updates, delete items from the start menu, or try to delete my Outlook deleted items folder.

It's definitely not an issue with Windows, as I've formatted and reinstalled fresh a couple times now with no change.
Can't see it being either of the hard drives's because the problems are there regardless of which HDD Windows is installed on.

Replaced the DRAM, and graphics card and neither had any effect at all.


What could it be?
PSU?
Motherboard?
One or both of the Hard drive's?

Don't see how it could be anything else.


Specs:
Gigabyte GA-K8NF-9
Opteron 170
2GB DDR400
CDRW
DVDRW
2x HDD's (WD1200JB, WD3200AAKS)
Geforce 7900GS
400W Enermax PSU

I don't think I'm putting to much load on the PSU, and it's run fine for over a year now.

Suggestions for what to try? Right now I'm leaning toward buying a new PSU, and hoping that resolves the problems... the only other thing I think it really could be would be the motherboard... would it cause such issues?

Any assistance would be greatly appreciated.

1. run harddrive diagnostic (download the files from WD website)
2. run a good antivirus program (search google for "AVG" and "TrojanRemover 6.1")
3. i don't think it's your PSU, it's mostly HDD.

System reboots as soon as I start the HDD diagnostic. Seems odd that both HDD's would be dying at the same time, but I'll put a different one in and see if that helps.
