After following the o/cing steps in the thread here, I managed to get a stable 270 x 3 with my Corsair VS running at 2:3 multiplier giving me DDR360. Two days back I rebooted my machine to install the new Forceware 81.94 for my 7800 GT and the machine refused to POST. I had to reset my bios for the machine to start. Thinking that the system is not able to handle the overclock(strange!!!), I lowered to 250 x3 and 4:5 multi and tried again. It booted fine and I went in to play NFS:MW. in Game I got a crash with the screen stuck and lot of artifacts on the screen. I did a cold reboot and again the system failed to POST. Once again I reset my bios and am now running everything at default speeds. Is my CPU forked???? Its only 2 weeks old, should I send it back and get a new one while I can or is something else the problem?
