Hi ...

I have my q9450 @ 3.2 and i've ran prime for over 8 hours with both small FFT and blend without any crashes or BSOD.

But i seem to keep getting a BSOD either during boot up or just by browsing the net. All my temps are within safe limits.

I have a ASUS maximus formula mobo with 1201 BIOS.

Do these settings look ok??

I've also ran memtest without any errors and i'm running 4x1gig cellshock memory.

Any help is much appreciated. Thanks.
