This is my build:
Motherboard: MSI B450-A Pro
Memory: 16GB @ 3200 OC
GPU: RTX 2060
CPU: R5 2600X
PSU: EVGA 550 Bronze

My motherboard has a set of error LEDs on the front for identifying common issues. Several times in the past two weeks, when I've tried to turn on my PC, the VGA error LED on the motherboard stays lit. The system does not POST. My monitor brightens slightly as though there's a connection, but no image is displayed. If I touch the power button in this state, the pc turns off instantly instead of going through a bootdown. Turning the PC off, turning off the PSU, unplugging it and holding the main power button for a few seconds fixes the issue, but it happens again randomly a day or two later. I've also noticed a slight decrease in FPS during gameplay across all games, and a slight increase in stutter. I've been using this build daily for just under two years.

Do I need to replace my motherboard, GPU or PSU?
