Msi z170a ez debug cpu blinking.

Build: I5 6600k- cpu
8gb ddr4- ram
MSI Z170A Pro- mobo
1080ti arous- gpu
600W evga- psu

I just replaced the gpu a few days ago, other wise this system is about 2 years old, no problems.

I left it running today and came back to the mobo blinking red at the cpu LED.

I did some research, I unplugged/replugged the mobo power cables- no luck I jockyed the RAM- no luck. I reset cmos by pulling the battery for 20 secs no luck.

Could this be a problem with the psu?
I plan on replacing the psu with a 750W.
If not that move to the mobo, then the cpu.

I think the same. Maybe psu, cpu, board.
