I just built a new PC and installed Windows 11 without any issues, and everything booted up to the desktop smoothly. However, after I looked away for a moment, the monitor went black, and now I can't access the BIOS or anything. Initially, there was a prompt asking to update the drivers, but I couldn't select anything because my mouse wasn't connected. After waiting for about thirty minutes for the screen to come back on and failing to see anything, I restarted the PC multiple times without any success. I noticed that the ASRock logo flashes briefly at startup, but then the screen goes black again. I've got a BIOS flashback button on my motherboard; should I try using that? I also changed my RAM profile in the BIOS to XMP 6000 since my RAM is 6000, but it was originally set lower. Any help would be appreciated!

If you can't access the BIOS, it sounds more like a hardware issue than a driver problem. Jumping the BIOS reset on your motherboard could help. I'd leave XMP off for now just to be safe while troubleshooting. Let us know how it goes!
Have you tried resetting the CMOS? Sometimes that can help restore settings that may be causing issues. Also, make sure to reseat your GPU and check the display cable connections. It’s worth a shot!

Thanks for the tip! I'll definitely give that a shot. It's a bit strange to me that it booted fine and then just went black, though. Seems odd, right?
