My friends' desktop PC won't boot, shows nothing on display, confirmed that everything's working fine, but BIOS is corrupted..need to flash the BIOS using bootable CD/USB (Hiren's boot CD or Ultimate boot cd or with similar utilities)
But unfortunately, can't even get into the BIOS to tell the PC to boot from CD or USB drive.
Alternatively, if I remove CMOS battery and re-insert it after some time and restart the PC, will this operation flash/reset the BIOS? so that, no need for bootable cd, and PC can start up.
Shall I try this alternative method? or Is clearing CMOS, not equal to flashing BIOS?
