Garrys mod automatically closes upon launch

About a day ago,my garry’s mod started bugging out.What happens is I launch it from Steam,it stays there as window for about a second,then closes.(It might be coincidence,but my firefox stopped working at the same time.)It just closes without a dialogue box or anything.
Not only did I restart the computer a zillion times,clean out the addons,and try to find a similiar topic,nothing delivered.


Have you tried a defragmentation?

Right click garrysmod, properties, local files, defragment cache files

If that doesnt work, Try a complete re-install

I have a simmilar problem, when i start Gmod up it crashes after 1 or 2 minutes, how do I fix that?
