My computer began freezing while i was in a game about two days ago. When it freezes, i am forced to shut it down manually by holding down the power button. At first, it would not freeze in safe mode and i unchecked any startup tasks that were not essential, which didn't help. Then, startup repair seemed to fix it until today. Now, after freezing during a game, it started to freeze during the launch process for safe mode and while windows was "checking my disks" or something like that. I was able to access safe mode once, however, and i uninstalled avast antivirus (to no avail) because I heard it causes problems.
