I recently went to toshiba manufacture to update my bios, and during installation, my computer froze and went black. I rebooted and it just stayed black, my bios didn't load. I couldn't use the recovery and applications/driver disc because it only works after the bios is loaded. techguy.org told me that it's my motherboard and that I ruined it. Is that true? I'm just getting a second opinion before I submit this into this repair store where I live.
