My friend has a Asus A7V8X-X mobo and is currently using an AMD processor that is 2.17~ ghz. In BIOS however, it sets the speed to 1.77ghz. When he changes the speed back to 2.17ghz and reboots.. he gets an error message saying that the ntoskrnl.exe is corrupt. When he goes BACK into the BIOS and puts it back to 1.77ghz, it starts up fine. Anyone know the possible problems? I was starting to think it could be a jumper not set correctly, but he said there isn't a jumper related to the processor.
