When i come to overclock it takes a very long time to get anywhere with it because every time it fails it takes a good 20 minutes before it will successfully boot again. During this time the PC will turn on but my monitor won't pick anything up, then after a while it will come on then go off again (for ~1 second) then come on automatically and boot properly.
Does anyone know why this is happening?
Surely failed Oc. When overclocking only increase fsb little by little, increase the vcore[by a bit], and check the temps.
For now, restore default settings, then attempt to oc again- reasonably.
