HL2.exe stops responding on startup

I tried to start gmod earlier today, stopped responding before I even got the facepunch logo.
PC Specs:
Intel core i7-3770
Windows 8.1 64 bit
Intel HD Graphics 4000

I’ve verified my game cache, tried -dxlevel 80 and -dxlevel 90 in startup properties, I’ve tried deleting local content then re installing it but nothing works

Try Updating your Graphics Card and delete gmod content Manually Deleting gmod from steamapps Insted from steam

What do you mean updating my graphics card? Updating my drivers?

I tried deleting gmod from steamapps, still the same.

Yes update your Drivers like your Graphics Card

Computer needed a restart, fixed
