Half-life 2 won't start after installation?

[Vestige]

Just installed HL2 today, I get past the valve logo and lambda, but on loading screen the game crashes. THOUGH I am able to play HL2 mods.
Header -> "HALF-LIFE 2: hl2.exe - Application Error
Body - > "The instruction at '0x139c247f' referenced memory at '0x0cabb018', the memory coudl not be 'read'.
Clikc to terminate program"
Any assistance would be appreciated. : )

Exit Steam, go to C:\Program Files (x86)\Steam\steamapps and delete the file "Half-Life 2 content.gcf". Then restart Steam and let it re-download the content again. Good luck.

I have already reinstalled steam and Half-Life2. Still I get the same error.

me too .

I tried to play Portal after installing it as well. And, the same error ocurred. This seams to be affecting all of my Steam games that are not mods.

sync half life with steam cloud, itll find any corruptions and script errors.

Syncing does not work either.
