Hello, I'm having issues with my motherboard, and here's my incident in detail:

I was using my computer as usual, went out to do some errands, and when I returned, my Windows was completely frozen. I performed a hard reset, but it didn't boot up again. The motherboard's VGA LED was lit in white, and nothing else happened.

After several reboots, I managed to access the BIOS, which had graphical errors (red spots all over the screen). I exited the BIOS, and it indicated that my Windows files were corrupt. Upon attempting to restart, it didn't even boot into Windows.

Things I tried:

  • I attempted to reset the CMOS. After doing this, the graphical error disappeared briefly, but it returned when I moved the mouse, and I couldn't boot into Windows again.
  • I also tried updating the BIOS, and the same happened: the error disappeared briefly but returned.
  • I visually inspected the components but didn't find anything unusual.
  • I tried booting from a USB drive with Ventoy, Hiren's Boot CD, and the Windows installer. I reached the Ventoy boot screen without issues, but none of the ISOs would load.
Before this, I had some electrical issues where the power went out, and when it came back on, the PC wouldn't turn on. I had to disconnect and reconnect all components to get it to power up. I measured the power supply voltages without load, and everything seemed fine. Voltage measurements from the BIOS were also within acceptable ranges.

My components:

  • ASUS ROG Strix B450-F Gaming Motherboard
  • AMD Ryzen 3400G CPU
  • HyperX Fury 8GB 2666MHz RAM x2
  • MSI Nvidia 1660 Super 6GB Graphics Card
  • Sentey SDP650-FX 650W Solid Power 80 Plus Power Supply
I suspect the motherboard is damaged, but I'm not sure. Any recommendations would be greatly appreciated.

The PSU is worse than junk and should not have been used anywhere near an add on GPU.

Remove the add on GPU from the motherboard ( MB ) hook the screen up to the appropriate video port on the MB and see how it goes.
