Garrys Mod Crashing on Startup

Hi, i was recently playing on my local TTT server, and then my screen froze, yet i could still hear everything within the game, i closed GMOD and restarted it, but the image i see will be static, but i will be able to interact with the menu, as shown by the mouseover sound and cursor. I have tried deleting and reinstalling GMOD, Verifying Game Cache, Setting launch to -autoconfig, and have even deleted and addons i had within my garrysmod folder! Any help is appreciated!
