CPU, mind of it's own?

[Jonesiani]

Hi all.

I turn my PC on this morning only to find on the post screen that my Q6600, (which was clocked to 3GHZ) has gone back to stock speeds.

Iv'e nad no crashes while it was at 3GHZ, and it was stable. It's recieving good cooling by a Zalman CNPS9700-NT nVidia Tritium.

The only thing i did yesterday was install Crysis.
I have a Gigabyte mobo, and 4gb 6400C4 Geil memory, windows xp (3.25gb effective)

What could have caused this?
Any ideas?

maybe installing crysis has altered chipset drivers, but i very much doubt it

not sure, leave it to someone else

My board does this if it has problems booting at higher clock speeds. Anything other than that?

When it was overclocked, id turn the pc on, it'd turn off for about 4 seconds, then turn back on again. Thats the only difference i noticed.

some motherboards automatically reset the bios settings if the overclock fails, instead of doing the whole 'open the case move some jumpers about thing'. my mobo has reset itself a couple of times even though it is completely stable, just overclock again

This is sometimes why overclocking is annoying when stupid things like this happen. Only thing I can think of is that the bios has defaulted. I doubt an install of anything at all will corrupt speed settings and bios settings. Unknown just overclock it again. Hopefully this don't keep happening.
