My Garys Mod keeps crashing any thoughts to help fix this. No I not gonna buy another processor .
when exactly does it crash? does it crash immediately after you start the game up, or after you undo an object?
It's just gMod. Mine crashes a lot. I it worked fine before, check if you enabled beta updates.
HL2.exe has stopped working: Welcome to the party!
Uninstall some faulty add-ons is my guess
