The game crashes... So this is something with the engine? Try updating your video drivers. Long shot, but you said you've already updated and verified your game/tool cache.

Try uninstalling-reinstalling. I know it can be annoying, but you can't move forward right now so....

Have you tested your ram?

Yes, Hammer and Portal 2 uses often 100 max. 500mb Ram. My Pc has 4 GB.

I really doubt it's the RAM. Typically when RAM is bad, the computer with BSOD and not just close the active program. But you can run memtest still, always good to make sure. Honestly, if I was you, I would have formatted my computer already.
