Where do I start

I am seriously impressed with the chip I have, I have got it to 3.82GHz @ default voltage of 1.525.



With all this glory comes some sad news, for which there is most likely a FIX

Windows XP just takes forever to bootup, everything runs dog s**t slow, this is anything past FSB of 300, then I get this, my system Windows XP, keeps coming up with an error "Windows has recovered from a device failure" you need to save work and reboot yada yada yada... my system then goes into 640*480 and I cant get it into a higher rez, I somehow have the feeling that the graphics is letting me down here.

I currently have the radeon set to 1.7v from the bios, It can go higer upto 2.2v, do I need to RAISE the voltage on the graphics?
or do I have a driver problem?

I am lost, any help appreciated.
