Thinkcentre M90p - Windows 10 Will Not Boot, Loop And Lag

I own a Thinkcentre M90p - Ive only added a NVIDA quadro 4000 and 16gigs of ram to the stock product.

Initially, I was wondering why it was over heating so i removed the CPU Heatsink Fan to check what the issue was, and cleared the dust. However when i did this, the bracket behind the mother board snapped. So i removed everything to get the fan+mount back on.

After i did that, the PC couldn't read my windows 10 HDD/SSD with error 1762 ... After struggling to figure out what to do with the equipment i had, I had switched around the drives... defaulting BIOS, however the WIN 10 kept saying it needed to be repaired. and the repairing took a long time. Ultimately failing and not successfully starting up... kept going in a loop.. FANs were LOUD and WIN 10 screen / repair screen / format installation was very very slow... BIOS setup screen wasn't laggy in comparison...

I ended up putting a SSD in a laptop and fresh installing windows on it.. and now that SSD is in SATA1 connection.

I have replugged all hardware at least 3 times.

I removed the BIOS battery piece correctly and reset.

I have attempted a HDD and a SSD that had fresh installs of windows...

I have unplugged power, grounded, 60sec power 30sec release 60sec power, replug..

I have attempted to run on less ram, with and without non-stock graphics card...

Basically I have done all the basic fix's i have found looking for answers from people with similar problems...



I am now at the point where I reinstalled windows home on another SSD and tried to boot it. I have removed the graphics card, any unused USB, have the two stock RAM sticks it came with, and I have tweaked with the BIOS to see if some settings will allow it to boot but the problem persists, where the FANs are LOUD, and the i am stuck at the Blue logo screen "preparing automatic repair". I will attempt to bypass the repair loop with command prompt but i have done that with my other SSD with no progress. This boot / reinstall / repair / please wait / recovery ~ all is considerably slow compared to initial screen with blinking ( I ) , and BIOS utility set up as well.. the repair either fails or the pc crashes on its own...

any help is appreciated, thank you for your time!
