This is probably not a very good issue to discuss but i thought what the hey? My friend decided to try and overclock his cpu and it backfired. His computer won't startup/boot. It turns the power supply on and flicks the light on once to the cd-rom and thats about as far as it gets. Does anyone know if it is possible to flash his bios from such an early stage or does it always have to get past the posts before you can flash the bios?
