XBOX One Day One Edition 2013 Power problem

[ThinkPad560X]

Over thanksgiving had nephew come over with his XBOX One S. Said it was loading slow. Put my hand on the top vent and it was very hot. Said I can change the thermal paste but would need to replace the 1TB HDD with an SSD if wanted it to load faster. Cleaned the board and shell and put new thermal paste on it. Got it back together and let him play for a few hours and it was running good again and very cool. A day later I figured I could get my XBOX One out and ran a game on it for a little. It was hot and probably defiantly needed the thermal paste replaced. "It did and was dried out" So I cleaned the board and added new paste. Put it all back together and set it up, went to power it on and no display but light came on with bing sound. Then 20 sec later it shut off with the bing sound off.

Took it back down stairs and took apart to see board and powered it on. powers on but CPU fan isn't spinning. It is very lightly trying to spin but isn't. 500GB HDD works, Blu-Ray drive works ejects and reads. Controller powers it on. CPU heatsinnk get warm/hot, So the CPU is running. I tried a 2nd AC Adapter and still same thing. I don't know what else is wrong. The only thing I remember is the Thermal paste "Corsair TM30" was kinda watery and wondering if it is shorting on the CPU.

From factory there was thermal paste laying in the trenches on the CPU. Same with mine after applying as I checked the CPU. I didn't clean it out as I put it back together without shell on and don't know what else is wrong with it.

I contacted a few places to see if they will diagnose the board and fix it but no one will as said it too old but they will fix older consoles then the XBOX One or newer. I do own a XBOX One S & One X but still like the use my OG One "The VCR"
I was going to get a 1TB SSD for it since I had it opened up.

I found this: https://www.ogxbox.com/forums/index.php ... mal-paste/
After reading this I see people are having the same problem after applying new thermal paste. I use a Qtip to clean the top of CPUs with the preferred Alcohol. I use a plastic "NOT METAL" pick to clean off old thermal paste on CPU and heatsinks. I just brought my XBOX upstairs where it is warm and dryer so if that thermal paste did have some kinda of liquid it can dry up over a few days.
My next option was going to get a replacement working board but I think your XBOX is registered to your MS account and think you would have to redo all that, Plus worry that the XBOX board isn't banned.
