After overclock, ntoskrnl.exe cannot be found


Nov 4, 2006
I'm attempting to overclock my Q6600 on my MSI P6N Diamond 680i board with PC6400 ram, but every time I change the CPU FSB and try to start windows, I will get the error that <Windows root>\system32\ntoskrnl.exe cannot be found. Can anyone tell me what this is a symptom of?

As soon as I load the defaults things go back to normal. I would really like to overclock, but I don't know what this problem stems from. I want to do just a modest overclock of taking my Q6600 up to 3.0ghz, but I can't even get it above defaults for some reason.
