Hl2.exe Error With Gmod after steam update

HI guys,

Recently there have been an update for Gary’s mod and CSS, after this update Gary’s mod crashes when its loading. Im getting the HL2.EXE error at both games.

I’ve already tryd to start GM with other launchoptions, updating my videocard drivers, installing updates for windows but it still crashes

My pc:

Intel Pentium Dual core 3.0 Ghz
Intel Motherboard( could’nt remember the correct branch)
MSI, Nvidia GTS 450
4 Gig ram
Windows 7

( I have no addons installed in Gary’s MOD)

I hope you guys can find the solution


Have you tried “Verify Integrity”? I had this problem with CSS earlier today, fix’d my problem.
