Garry's Moc Crashes half way through loading screen!

Specs:
Video Card: GTX 280 (Latest Drivers)
Processor: Core 2 Quad 2.4 Ghz
RAM: 4 GB (3.2 Usable, stupid crap motherboard)
OS: Windows 7 Ultimate 64 bit

I need help, the last thread shed 0 light on my problem. I have cleaned gmod, reinstalled it, deleted it, re downloaded it, -dxlevel 81. Nothing is working!
Only today this is happened and I am panicking for my gmod. D:

Aw, I can’t change my typo on the thread name. (Garry’s Moc) Rofl

Nevermind, I fixed it, all I had to do was restart my computer. An admin can feel free to close this thread.
