Gmod Restarting

my gmod restarts my computer when i play it
before the new steam i had a code in the launch options
but it was wiped when the new steam came out
the code was something like this : dvlevle8
if you no the code or can fix it another way
tell me

-dxlevel 80

Have no idea why a directx conflict would restart your computer, but it’s worth a shit to whack that in.

it was something like that

No probs, working now?

i have not tried yet
i am doing some important work
studying for exams

Ok, good luck with that. If it’s still fucking up when you try that, post back or PM me.
