I was attempting to update UEFI BIOS on my ASRock 970A-G/3.1 from the download for my mobo on the ASRock website. I was doing this due to my computer randomly shutting down for the last couple of weeks. I had originally tried removing my new GPU that I got and putting my PC on top of the desk rather than in it's cubby(just in case it was overheating). When it continued to power down, I did every virus scan available from Windows defender. Nothing was found. I don't suspect my power supply, as it's a relatively new 750w. So I compared the BIOS version to the latest one in the website and it appeared to need updated. So I downloaded their BIOS updater and ran it once. It proceeded to fail and tell me not to restart my PC until it succeeded. So I closed all the windows on my PC and tried again. Shortly after beginning, my computer froze and I patiently waited for 1.5 hours, watching YouTube while sitting in a discord server (all on my phone). My friend proceeded to get online and when I told him I'd been waiting that long, he said it was bricked. At first I denied it, but he insisted to the point I doubted my opinion. So I powered down before any resolution happened. Now it is DEFINITELY bricked. I don't know if it had already been, but that's neither here nor there at this point. I'm just wondering if, with my mobo, I can use a USB flash drive to force BIOS to reinstall.
