Pc worked, now it doesn’t R.I.P

  • MB: Rog Strix B550-F

  • Cpu: Ryzen 9 5900X

  • Aio: Emermax Aquafusion adv 240

  • Ram: Kingston Fury Beast 16GBx2

  • Aio: Emermax Aquafusion adv 240

  • Gpu: MSI GeForce RTX 3060 12g

  • Psu: CoolerMaster mwe gold 750w 80+

Everything was running perfect. And the logo on my aio was upside down ( been like that for 2yrs ) but today it was bothering me. I decided to fix it. Disconnected the aio and cleaned it up put new thermal paste and reinstalled. Computer would run for about 5mins then say the cpu was overheating and would blue screen. Took it off again checked all the connections, cleaned up and added new paste and a bit more this time. Same thing.

Then took the aio out again ( the cpu came out with the aio and 2 pins were bent nothing crazy but fixed them and cpu slides in like normal ), took out the memory, and gpu. Checked the connections to the psu, and reinstalled everything. Now there’s no display, and the MB qleds don’t light up which let you know of issues with parts on the board.

Ive checked connections , I’ve reseated the memory, tried using only 1 stick, I tried using the onboard graphics. I’m at a loss.
