[SOLVED] Displays cannot detect machine

[awesomeish44]

Mobo: Asus p8z77-v lk
CPU: intel i7 3770k
Gpu: GeForce GTX 1060 6gb

I originally built this machine in 2013, and upgraded the GPU in 2016. About 9 months after the upgrade, my machine shut down on me while it was running the same game I always played. Ever since then, the machine will turn on, but the displays won’t detect it. I’ve connected the display to both the GPU and the motherboard but there’s no change in behavior. I upgraded the PSU, I’ve tried with multiple monitors which all have auto detect, but still nothing. Since I’ve replaced the PSU, and since both the mobo and GPU cannot be detected, I’m thinking this might be an issue with either my mobo or my CPU, but I’m not sure how to figure out which it is from here. Does anyone know of steps I can take to diagnose this further?

Thanks in advance!

Try cleaning and reseating the RAM modules... also try with one module at a time.

Reset the bios.
Breadboard the system.
Take the motherboard out of the case.
Add components listening to the speaker until you find the culprit.
