I just built my first PC.

Upon every boot, all 4 EZ Debug LEDs (CPU, DRAM, VGA & BOOT) are flashing red 1 by 1, then after a few seconds, they stop.

 

I really don't understand why.

Everything works - I can go to the BIOS, Windows installed successfully, all drivers installed, works flawlessly.

 

Specs:

CPU: R5 3600

GPU: RX 5700

RAM: Gskill Ripjaws V 16GB 3400MHz

SSD: Kingston A2000 500GB

MOBO: MSI B450 Tomahaw Max

Your bios is going through booting procedures and checking all parts working how they supposed to work. If there will be problem with any components than the light would stuck on constantly showing which component causing problem. Nothing to worry about everything working how it supposed to work.

Thats the normal booting procedure, my Tomahawk also does that. When i had a bad GPU (needed to RMA`d it) the  VGA debug LED was always on and no video was showing, so thats how they work

This forum helped a lot, I'm a brand new builder too with the same hardware except I have a 2600. I didn't know much about trouble shooting and i have been trying to find answers. So it is safe to keep using my PC when all four lights just flash on 1 by 1 at every start up? If this isn't the source of my PC having unexpected shutdowns and sometimes not booting, would anyone know whats causing issues. (I think it might be the PSU, but I'm not an expert)
