Every now and then on startup I get a little message asking if I want to download the new BIOS. I pressed the first time, expecting to get a file saved somewhere, but the dl failed, and I started to ignore it. But since then, not often but sometimes, on startup I get blackscreens and it takes a long while before the screen shows things. (Not the monitor, have tried with multiple) So where should I download the new BIOS version, and how should I install it? Thanks!
