Windows 10: PC runs extremely slow after booting up a game on Steam, How do I fix?

In the last 2 months I've been plagued by issues with my PC. 2 month ago it would crash constantly with no reason, 1 month ago after the initial crashing stopped it would crash after 5-10 mins of playing a game on steam. Now after updating my BIOS, checking for malware/viruses, updating to windows 11, checking RAM stability, checking CPU and applying new thermal paste... it now runs insanely slow after booting up a game on steam. I reinstalled steam checked thru its files and the games I was playing, but have found nothing. My last ditch effort was resetting the PC but to no avail, I am at

Steam And Games Not Running.

Hi Shivam,

Thank you for posting your query on Microsoft Community.

I understand that you are unable to launch games. We will help you to resolve the issue.

I would appreciate if you could answer a few questions to narrow down the issue.

• 
  Did you receive any error message?
  
• 
  Are you trying to launch the games using Microsoft Account?
  

I suggest you to, place the computer in
Clean Boot state and then try to launching the game.

A Clean Boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update or when you run a program in Windows 8.1, Windows 8,
Windows 7, or Windows Vista. You may also troubleshoot or determine what conflict is causing the problem by performing a clean boot.

Please refer the steps given in the link below to perform a
Clean Boot:
