All of my games lag and most crash when I try to load into a level, even Steam games, the only exception is Clicker Heroes which doesn't lag at all, games with low visual settings don't crash (Like the game "Rake") but instead lag extremely and it isn't getting better
Other Info:
It's only affecting my computer (Tried a friend's laptop - no problems so it can't be a problem happening at Valve or Microsoft)
I've tried:
Deleting a lot of stuff on my computer, when I started it was at least 840GB now it's 822 GB, it didn't lag at this level before but it is now
Updating everything on my computer (Including the display drivers)
Verifying the integrity of the game files on Steam
Restarting my computer
Shutting off my computer and turning it back on the next day
Uninstalling and reinstalling the game
