Can't boot pc

[ThatGuyOnPC]

For the past few weeks my PC has been acting weird, in order to boot it, I had to wait for it to go through multiple attempts, and now, it takes a while to boot at all, and when it soes, my monitor is blank, my keyboard and mouse unresponsive and there is a red led on the ez debug on my motherboard indicating that my cpu had failed or something along those lines. I'm lost though because it's been working fine for the past year and I don't know what could've caused this, any help would be appreciated, thnx.

Always list you full hardware spec + what kind of OS you are running when posting a question.
Almost impossible to help without knowing this.

Have you built this system yourself?
If yes: How mutch thermal paste did you use?

Do you have an spare PSU laying around? if so try and connect it and see if that fixes the problem.

Yea I built the system myself, although I used the stock cooler that had thermal paste pre applied, so I didn't add any, and my cpu had been working fine for the past year, so I'm not sure what would've caused it to suddenly stop working. Don't have a spare psu lying around either, but my motherboard and graphics card all seem to be getting power so that might be a good sign.

Get some spare thermal paste. I recommend Thermal Grizzly Kryonaut.
Take the whole system out of the case, and test build outside of the case with the bare minimum of hardware just to be able to boot up.
Take the CPU out of the socket and re-seat it again also.
(when you apply thermal paste 1 or 2 small dots around the size of a rize grain is enough in the middle of the CPU)
