Garry's Mod opens and closes with "hl2.exe is not responding"

[Dredlock11]

SPECS: i5 4440 Quad Core @ 3.1 GHz, 8 GB of RAM, R9 280, Windows 8.1

I've tried these:
Verified Game Cache
Ran lots of different launch options
Disabled Firewall
Joining a friend
Turned PC on and off I again
Updated drivers
Deleted the garrysmod folder and re-installed it

I have NOT deleted all of Garry's Mod yet. I don't think there is a need for that yet.
Anyways, here's the timestamp:

Verified other source games' cache. And Garry's Mod works now. Sorry for your time.
