Laptop black screen, fans go to max. Cpu dead or not?

So I’ve been running my dsanke modded p870km1 for some time now and ran into a slight problem. I have a 4.7 stable 8086k as the CPU. Recently after a BSOD computer won’t start. Reseating the cpu causes the screen to stay black on boot as well as fans ramping up to maximum after about 30 seconds. I also notice that when the fans start to spin, the power LED goes Amber and starts blinking. Currently swapped in my 7700k to keep the laptop running but I want to go back to my 6 core.

 

So is my coffee lake dead? Tried reflashing the dsanke bios.

Does the CPU heats up when starting the laptop?

Yes it does. I did remove a whole bunch of gunk from it (the stuff that blocks Liquid Metal from sticking) but it does heat up.

So the cpu is delided? If so check the actual chip for cracks. I had the same experince with my 9900k (but mine had a fine crack all across the chip).

Can't see any cracks but if my 7th gen is working I guess it's the CPU. Now to find another 8th/9th gen for cheap...

 

In other news, how do I remove the TM heatsink screws? One of them is stripped and I want to replace it. Currently using my old KM heatsink.

I used a very thin pliers and rotate the screw a little bit loose.

I should clarify that I already took off the heatsink from the board. I just want to get rid of the screws on it since I don’t want to buy another heatsink

They  have a security nut near the thread. Remove that security nut and the screw will come off.
