Some times when I turn on the PC, the BIOS is accessed all of a sudden without me pressing a key. I have a Asus z97 Maximus VII Hero motherboard. Any idea why this happens?
This could happen if CMOS battery is low, CMOS gets corrupt and you get a message from the bios to press F1 for bios or F2 to continue
Is the date & time correct when this occurs ?
