Colors on boot up and A6 error code, is it the motherboard or the CPU?

[r1s8k]

Hello,

 

My PC broke yesterday, I was playing Borderlands Pre-sequel and during the game, everything just froze up, no response for anything. So, hard resetted the PC, started it again.

 

The screen is playing different colors, red, blue, white ... etc. I thought the GPU is broken, then I disconnect the GPU, started the PC again and the same result, I noticed A6 code on the motherboard notification LEDs. So could it be the motherboard or the CPU?

 

I also disconnect many parts like HDD, Audio ... etc, same results.

Could you list your parts please? Exact model numbers please. Error codes and their meaning aren't universal.

Can you remove the gpu and try using intel integrated graphics?

I tried yesterday, I also removed all HDDs, front case USB cables and Audio cable.

 

Same result.
