I was getting an occasional Blue Screen of Death on my main computer. I contacted HP for help. I learned that the BIOS can be updated from the control panel.

See the first method listed: Update the BIOS automatically using Device Manager
I think this will work even with non-HP computers. If you try it, please let us know.
I normally use the HP Support Assistant method, but of course that is for HP stuff only. It didn't find any updates today. The Device manager did.
Don't know if it fixed the problem yet.
Tnx & 73,
