My computer freezes whenever i fullscreen a game and only when i fullscreen a game

A week ago my computer ran completely fine with no issues what so ever. One day my computer bluescreened and windows somehow got corrupted and i had to completely wipe my main drive and reinstall everything. Ever since then i cant play any games in fullscreen without my pc freezing for a few seconds then unfreezing and then once again freezing and it just repeats itself forever. I can play any game just fine in windowed mode but if you press the square in the top right to fullscreen the window it immediately starts freezing again. I can use any other application in fullscreen mode without it causing issues its only when its a game.
My computer specs are:
AMD Ryzen 5 3600 6 core cpu
32 gigs of DDR4 ram
1 terrabyte 970 evo samsung SSD
few seagate harddrives
NIVIDIA RTX 3070 gpu
i dont know what else i would need to give information wise so if im missing anything please let me know

I havent tried alot of things since i dont even know how to address the problem. It seemingly works just fine with about everything else but issues only arise when i start trying to play a game. Also, the game i have been trying to play was lethal company which isnt a very big or demanding game to run i also tried minecraft and valheim. All 3 didnt work and just started freezing only when in fullscreen mode.
