Help Restarts

[neocon]

Was playing COD4 and got screen lockup, had to restart

Then windows reboots with high pitched whine and freezes

I took overclock off and restarted, everything ok, bam restart

any ideas?

my temps seem normal when I check. overclock has been fine for over 1 year at 2.8ghz. anyway, i managed to tyoe this before it freezes.

yes its stable

its not even a big overclock 50c-60c under load

i had a problem with an audigy 2 once, where if it was placed on *** bottom pci slot it was cause restarts
