Cause: Installed my own modded BIOS. The original was downloaded from manufacturer. Symptom: Monitor power light keeps flashing without displaying POST or anything. Tried pressing CLR CMOS button but nothing changed. Also put the original official BIOS in USB drive and press F6 (USB keyboard) in attempting to re-do. I have now two options: 1. Go for support service. 2. Use the tricks here: BIOS Recovery procedures htt p://forums.mydigitallife.net/threads/870-Bios-Recovery-Procedures ????? HELP!!!!
Update: The MB was sent to support service today. The MB was first boot using my own CPU & RAM. Dr Debug last showed "60" or similar figures. The technician replace the RAM with his own. Dr Debug showed new figures "5F" or similar. He then pulled out the CMOS chip and flashed it with lab equipment. When it was placed back, Dr Debut remained at "00". He then reflashed it again with another version. Dr Debug remained at "00". He then certified the MB. I am now waiting for replacement.
Did the BIOS mod kill it? Or did the BIOS flashing procedure fail (i.e. it would've happened even with the official BIOS)? Or was it already faulty before flashing and would've died even if you had never attempted to flash a modded BIOS? I couldn't really tell from what you wrote and I'm considering flashing a ASRock Z77 Extreme4 as well.
Wrong procedure adopted in generating R/W report. The BIOS CMOS died. The MB was returned for maintenance.
