hl2.exe stopped working - stops loading at initialising clientmode

[audiotragedi]

Need help with this.
I bought GMod a few days ago, I went to load it again today and it suddenly stopped loading and came up with the typical error message that most of us have encountered at some point; "hl2.exe has stopped working".

I tried loading it again to find out what could be and it stops here;

initialising clientmode.

I uninstalled the game and re-installed it and it still keeps coming up with the same error at the same time when its " initialising clientmode".

can anyone help?

EDIT: yes I do realise the icon should be changed to the help icon
