Garrys Mod-10 wont start

when i try to play Gmod always says.

hl2.exe has stoped working.

i used to have to be quick and right when it opend up i would have to open task manager and then hit the ‘switch to’ button and it would let me play it…but only Gm_Flatgrass. But now it just updated and now even by doing what i ussualy do i cant play it at all.

and also is the starting screen supposed to open up looking foggy then clear away? cause mine automaticaly is clear.

I just tried unistaling the game then re-installing it. but it will still not start.
