Dear all, I was intending to OC my CPU to 3GHz. I refreshed the BIOS of my EP45-UD3R and installed Windows 7 64 Bit. But whenever I start running Cooling down test w/ Prime 95, my Windows would freeze. (Thus I cannot do screen capture... I have to use my digicam to take a pic). Can someone kindly advise what seems to be the problem and if I should continue to OC. Many thanks.
