It's always recommended to backup your BIOS before flashing it so I'll presume you ignored that step. You could visit the MSI web site and download a previous BIOS version and see if you can re-flash and resuscitate your MB. Sometimes these things are not reversible and BIOS chip replacement is the only option. At that point, a new MB might be less costly.
I have a MSi P67A-C43 B3 and recently I just used the MSi Live Updater 5 to update some things, BIOs update, from 1-h to 1-j I believe and some other ones like the realtek drivers.... I forgot since the last time I used it it totally crippled my system and I wasn't able to boot and now it has done the same again. What a mistake I made....
Anywho, I would really need some help getting my computer to boot up again.
I press the power button and the screen just stays black, nothing loads or pops up, everything runs fine, all the fans are on but nothing happens. I'm so lost and confused and worried
I have tried to clear the CMOS, jumping it, pressing the clear cmos, taking out the battery for 3 minutes. Nothing has worked so far. I don't really know how to flash a bios, maybe that will work? Could someone please instruct me
