Hi, i just upgraded my cpu from an intel q6600 to a qx9650. now when i try & boot into windows 7 i get a bsod & the comp restarts so quickly i cant even get the error codes. i have made sure the motherboard can use the new cpu & updated it before installing the new chip. the bios also picks the cpu up with no problems. I tried the windows recovery but that bsods too. Also tried installing win7 on a formatted hard drive but this also bsods! The most confusing thing is that it works fine with an xp install so i'm not sure i can say the cpu is at fault & send it back for a refund. Any idea's anyone?
