I am having trouble figuring out how i accessed my advanced BIOS screen. Its hidden and contrary to what i've read, it CAN be accessed. I know because somehow i accessed it the adjust the power settings and clock speeds etc. Does anyone out there know which key combination it is? it is NOT f1, f2, f10, f11, esc or del. Please help.
