I was using my PC for about 10 minutes when I noticed that Spotify was glitching out, and then everything suddenly froze. I ended up with a black screen, almost like a reset, and now it keeps rebooting straight into the BIOS without letting me out. I've tried removing the CMOS battery, RAM, and GPU—this has helped me in similar situations before. For context, I usually unplug the PC for surge protection while I'm away, and I've recently had a couple of power outages. Just to be safe, I disconnected the PSU overnight. I'm sharing all this because I'm worried about my setup, especially with the high costs of RAM right now.

It sounds like a tricky situation! If your drives are showing up but you're still getting the 'No Bootable Device Found' error, it could be worth checking if your boot order is correct. Sometimes just switching the order can do the trick. Also, consider whether you might have a damaged boot drive—that could be the culprit right there!
First off, check if your OS drive is actually being detected. If it is, go into the boot tab and make sure it's set as the first option. Sometimes toggling between CSM and UEFI might help as well. Make sure all the cables connecting your drives are secure and undamaged. If it's an NVMe drive, try reseating it. If nothing works, it could be a sign that your files are corrupted or even that the boot disk itself might be failing. Good luck!
Thanks for the tips! But just so you know, I have no idea what CSM or UEFI is. I should mention that when I remove the GPU, RAM, and CMOS battery, it works for a short time before shutting down and going back to BIOS.

Thanks for the suggestions! I’ll look into the boot order as well. I really hope it’s not a hardware issue since I don’t want to go through replacing anything right now.
