HL2 and CS Source works fine on my system (similar to yours) but it crashes on launching HL2 Death Match. Spoke to support, but they don't know what the problem is yet. Expecting a call-back.

Application hang means the request sent could not be completed.

This would cause a problem with Half Life since Steam is needed to run the game. I would say they are very related.

I would check to make sure you have the most recent version of both Half Life 2 and Steam. I usually turn off steam whenever I can, only because its a resource hound.

Hope this helps.

Did you ever resolve the crashing issue with HL2 on your system ?

Phil.

Just for kicks and giggles, do me a favor? Exit out the Steam and launch the game again.

Still having problems...

I reloaded HL2 and steam and I am still crashing during loading (at the Valve face). I hear music, see the face, then the screen goes black...and fails to respond. I have to turn off/on to restart.
