I've never seen this before but maybe someone else has. All I did was raise the multi from 11 to 11.5 and vcore to 1.98v taking me to 2366mhz. It primed for a few hours just dandy. So I get on and I'm working in MAX with this forum open in the background, and winamp playing the "lovage" cd from heavy. (damn good cd btw) All of a sudden the system won't register any mouse clicks, and the screen gets quite a bit brighter. Music's still playing, and then eventually it makes a BEEP noise from the speakers and it totally locks up. Music was still playing until I shut it down. I backed it down to previous settings and its going ok now. I've never seen the bright screen incident before. My 9700pro was at default clock as well. I do remember that when I was moving between 205 and 213fsb with mem in sync, the system crashed and needed a reboot from windows. When I got back in it blamed it on the 9700pro for some reason.
