Hello. I just came back from being away from home for 3 weeks, and my PC will no longer boot to BIOS. This is a problem that has become worse over time. When I first built the PC in August 2020, the PC would sometimes freeze around login/desktop on startup (reinstalling windows had no effect). Then it started not even getting to BIOS. Usually restarting would work, but now nothing does. Now my monitor doesn't even get a signal.

What I've tried:
  • Replacing and resetting CMOS battery
  • Replacing PSU
  • Checking to see if all cables are correct, inside and outside of the case
  • Tried with another monitor
  • Reinstalled CPU to check everything was ok there
  • Tried booting with and without my SSD
  • Tried different RAM slots and each ram slot individually
  • Tried a different GPU
  • Booting with and without peripherals
So, considering I've swapped every component except the CPU and Motherboard (the CPU which I checked), is this a faulty motherboard issue? It wasn't cheap and I've only had it for a year...

My specs:

AMD Ryzen 3600XT

AMD RX 5600XT

16GB RAM

Crucial P1 1TB SSD

Gigabyte B450 Aorus Elite Mobo
