I think I killed my 4790K when I delidded it

[cfrhoar]

I used the Rockit Cool 88 delid kit and everything went smoothly. I applied thermal grizzly, put the IHS back on with the provided guide tool (I did not re-glue the IHS back on) and then popped it back into my system. The MB turns on but I get post code 'C'. I double checked the EPS power cables and everything was correct.

I also tried to reset BIOS, took out CMOS batter, tried separate BIOS on the MB, tried 1 stick of RAM... still gives me 'C' for post code.

The die looks fine as well as the PCB on the CPU. I do not see any bent pins on the MB.

Here are pictures of the CPU and socket: https://imgur.com/a/bYCIz

I'm okay(kinda) with loosing out on the CPU but I want to how I ****** up so I can correct it next time. I feel like I have tried everything but I want to make sure I'm not missing something before I upgrade

MB is a EVGA z97 classified

TIA for any help or recommendations.

Thank you for the replies everyone, I did notice the hair in the socket and removed that. The missing liquied metal on the endge of the die was because I was in the process of cleaning the liquied metal and reapplying it so it was not like that when I was testing it in the MB.

Is that a scratch?

I did notice that, it is not a scratch or liquied metal (im honestly not sure what it is because it took quite a while of rubbing it with a mircofiber cloth and isopropyl alcohol to get it removed.). I cleaned it off and retested but still no dice.

Thanks again everyone, I’ve went ahead and upgraded to the 8700k and will NOT be attempting a delid . I will also be testing the PSU soon just in case moving it out of the case caused it to break .

and the best guess to what happened would be whatever that stuff was by the little capacitors was conductive and cause a short on the traces of the pcb?

Did you put anything over the smd's like nail polish?

I did not
