I just built a new system in my old case. It is a Gigabyte B550 Aorous Pro V2 with 16 G of RAM and AMD Ryzen 5 5600G with WIndows 10 loaded on M.2 NVME SSD 1 T. It has worked for a few days and then I came down yesterday and neither monitor would come on. They were powered up and the computer was running, but I couldn't get anything on the screens. I tried shifting where the cables were plugged in and eventually removed the video card (Radeon HD 5770). The fan in the card was unusually loud when I first discovered the situation. I have been able to boot to BIOS a couple of times and reset the CMOS twice. After the first time I reset the CMOS, I was able to enter the BIOS settings and confirmed that the boot order was correct. I set it back to Fast Boot because I had read that the M.2 wouldn't work properly if that wasn't set. However, it still didn't work. At least twice it got as far as the Windows troubleshooting options, but the first time I just told it to reboot and it returned to the same problem. The next time I attempted to have Windows diagnose and fix problems, but when it rebooted it would not go to Windows and only showed the opening BIOS screen. I have reseated the RAM, disconnected USBs except for the mouse and keyboard and I removed two cards I had installed for extra USB ports and TV. Initially the reset button on the computer would flash after I tried to reboot, but it eventually stopped doing that. Most recently, when I plug the computer back in and press the power button, it lights up and runs the fans, but the LEDs along the bottom of the board do not light and the power switch will no longer power down the computer when I hold it down. It is all powered off right now and unplugged. I tried using the install flash drive to boot to, but it isn't even going to the BIOS screen anymore, so no good. The power supply is a Thermaltake TR2 RX 850W and it is probably 10 years old, but it should have more than enough power and has shown no signs of failure until now.
I am not sure what else to try at this point - it seems to get worse as I do troubleshooting. Any ideas will be appreciated.
