Hi, I was updating my bios to v1.5 from windows because I had no USB stick available and because it always worked fine when I did that. While installing my system rebooted but then when it turned on I got only black screen.. No bios not anything. LEDs are on, fans are on..looks like PC is going. After while it shuts down it self then start it self again..and all over again. Should I take out batery from mobo or what? I knew I shouldnt mess with updates this late at night.. Sigh :(

My system is listed bellow

Your main BIOS is corrupted, switch to Backup BIOS

I have tried clearing CMOS but I have no idea if it did something because I have still the same problem, Im not sure how to boot that bios from USB.. it downloaded some file from MSI called E7821IMS.150 .. I renamed it to AMIBIOS.ROM as they suggested on MSI site.. tried to hold F2 while starting PC or CTRL+HOME, and all F keys ... nothing helped
