I recently encountered a really frustrating problem with my first PC. It just stopped working one day out of the blue. Here's what I have in it: an AMD RX6800 GPU, a Ryzen 5 7600 CPU, a Gigabyte B650 Gaming X AX motherboard, 32GB Crucial RAM, and a Thermaltake 650W power supply. When I turn it on, it shows the Gigabyte menu but won't let me access the BIOS no matter what keys I press. After about 3 seconds, the screen goes black, and my monitor says 'no signal,' but I can still hear the Windows sounds, which suggests it's booting into Windows. I've tried a few things: changing the HDMI cable, switching to integrated graphics by removing the GPU, somehow getting into the advanced repair options but being unable to access the BIOS, and even removing the motherboard battery for 30 seconds as suggested. Right now, I think it might be a failing motherboard, an issue with my GPU drivers, or something wrong with the GPU itself. I'm considering sending it for repairs, but I want to know if there's anything else I can try first! What are your thoughts?

If changing the HDMI and trying different RAM slots didn’t help, it’s worth checking if there are any firmware updates for your motherboard. Sometimes these can cause weird issues, especially after fresh installs or hardware changes. If you have a USB drive handy, create a bootable drive with Windows installation media, restart the PC, and try booting from it to see if you can access the BIOS that way. If you're still having trouble, a faulty PSU can also cause similar symptoms, so if you can, try testing with a different power supply.
It sounds like the issue could be related to your display settings or a BIOS/firmware problem, rather than a complete hardware failure since you can hear Windows booting. You might want to try using a different monitor if you can, or booting in Safe Mode, which will enforce a lower resolution. To do that, power on the PC and as soon as you see the Gigabyte logo, force a shutdown by holding the power button. Do this three times, and on the fourth boot, it should take you to Advanced Startup Recovery where you can choose to enable low-resolution video or Safe Mode. If you manage to get video, it might just be a driver or resolution setting issue. Also, don’t forget to check your RAM—faulty or improperly seated RAM can cause boot problems. Try reseating your RAM and booting with one stick at a time in different slots to see if that helps!
