is this a laptop? if so most likely the vendor who made the laptop put a locked BIOS on the laptop so you cannot oc the cpu....can you give me the make and model of the laptop?
yea man sorry...you are SOL when it comes to OC'ing your cpu...your BIOS is locked there is pretty much no way to get around it....besides overclocking on a laptop is not the best idea older laptops run hot as heck already so you would just be adding to that
