Garry's mod crashes when I open the console.

Help. My Garry’s mod crashes whenever I open my console. Please help!

It might be a font issue. What OS are you on?

Here are my specs:

Operating System: Windows 7 Ultimate
Processor: Intel Core i7 4790
Graphics Card: MSI GTX 750Ti Twin Frozr
RAM: Kingston 16GB 1333Mhz
Mother Board: MSI B85M-G43 Military Class

I tried changing the dxlevel higher then 90 already. It didn’t work.
