Did I brick my CPU during maintenance

Hi guys, I could really use your help. I was doing normal maintenance as always after roughly a year of not touching the PC. I disassembled everything, changed thermal paste on CPU and put the cooler back on. Cleaned all the dust etc. Normal stuff.

When I was changing the thermal paste I noticed there was some paste around the CPU and on the bottom of the CPU so I cleaned it with wet wipes (I was very gentle using IFIXIT tools to rub the paste away of the CPU; wet wipes contains less than 5% of cationic surfactants, less than 5% non-ionic surfactants, phenoxyethanol, potassium sorbate). Then I put everything back together. 

I tried to boot up the PC but I got into a boot loop with CPU error (see attached video). I'm afraid I bricked the CPU. Do you have any tips for me what to do next? So far I only cleared CMOS but that did nothing. 

I will most likely go ahead and buy some cheap CPU at local shop to test if everything else is working (we have 14 days return policy if you buy stuff online, so I plan on abusing that).

Thanks for tips!

Yes, you can see it on the top left corner of the video. I will try play with it though. Good tip.

We can't see the video, it's private.

 

Did you remove the CPU from the socket for cleaning or left it in?

Video should be now visible. And yes, I took it out. Making sure I do not bend any pins or anything. Always very gentle with these.

Dirt on the CPU/socket or a bent pin are the most likely issues...

How gentle do I have to be while cleaning the bottom of the cpu? What precautions should I take? Cleaning with alcohol only?

It is best not to tough it at all. 

 

When I upgrade I know that there is a chance that it could go wrong especially with an Intel socket. It has happened twice to me. Once with an LGA 775 and once with a LGA 1151.

 

Also the CPU could be find and the motherboard could be trashed. That happened once to me.

  

I literally hate what Intel uses as a socket and love the good old fashion socket AMD uses.

Ok so I managed to post and boot into Windows now. I cleared the bottom of the CPU with tissues and rubbing it with my finger. I don't know what did it. It is midnight now, I will mount the cooler tomorrow morning and hopefully there won't be any more issues. Thanks boys.
