Post-move woes - thermal grease re-applied, no boot

Build is a Asus p8h67-i deluxe and a i5 2500k, Silverstone SG06 case.
I just moved.
When I setup the PC I started to get CPU overheating errors from BIOS on bootup, up to 87 Celsius.
Since it had been 1.5 years and I was afraid the grease had broken up, I decided to reapply thermal grease with AS05 and used lint-free gauze and Isopropyl alcohol to clean off the HSF and CPU.
I'm not used to the heatsinkfan and struggle with installing it at first. something could have occurred here.
I was lazy and did not unpack my static band.
After replacing all the parts I pushed the button.
No boot. No power light. No fans, including PSU fan turns on.

The light on the motherboard is on.

I grab a paperclip, test the PSU and fans turn on. PSU is good.
Replaced cmos battery. Still no dice.

Now I'm curious, is it the CPU or the motherboard I fried?

Either stick show a red DRAM led. Same status as before. No PSU fan goes on, no case fan goes on. CPU fan doesn't startup. Power LED on mobo is on.

Well, this is strange.
You say you moved but the cooler you use is the standard, it's so light that it couldn't possibly bend the pins in the socket.
Here's a couple things that jump to my mind about it:

Bad thermal paste application: you used a conductive paste, too much of it, it leaked into the socket or pcb, it shorted the cpu.
Bad heatsink removal 1: when you tried to pull it off, you applied undue pressure on a corner of the cpu, which pressed too much on some socket pins.
Bad heatsing removal 2: you pulled it carelessly and knocked off a capacitor (unlikely)

And one last thesis, although I do not know if this makes sense: On FX boards that were made before the FX arrival, you needed to update the BIOS in order for the mobo to recognize the cpu. I dont know how do H67 boards work, but maybe you corrupted your bios by power instability and it got corrupted.

Try clearing the CMOS, by swapping the CMOS jumper to the clear pin and try it, shut it down, then go back to the normal mode pin and try it again.

Yup, agreed with commander. Boot issues are usually solved this way, unless something went wrong on the hardware level.

You stated having issues trying to remove the cpu or putting it on I would check for bent pins as05 in the pin holes reset cmos battery also check all your cables make sure everything is seated and plug in I had a pc that did something similar one time come to find out the power for the board was seated all the way down my bad that's yrs ago.

Hi Commander, thank you for your reply. This solved my issue. I didn't have the jumper since I inherited this a year ago but jumped it with a paperclip :wahoo:

No problem, and awesome, Ive had times where the system would half-boot, where lights went on, but nobody was home, so I clear the cmos, and it booted fine after.
