Gmod crashing at start up

Ok so since yesterday, I installed counter strike source on my pc (new pc) so I tried booting up gmod to play with friends and it always goes to the blue screen before it says facepunch studios and crashes
I already tried changing my resolution for the game on launch options, already tried uninstalling and installing the game multiple times and nothing happens, I already deleted counterstrike and tried booting the game up without it and nothing, I also tried to defragment the game and nothing any help?
