My Half Life game won't run on Steam

When I play the game, I get a window saying "The game has detected that the previous attempt to start in openGL video mode failed. The game will now run in software mode." The game doesn't even run at all. Here are my specs:

CPU : Core i5-3350P 3.1GHz

Graphics Card : Radeon HD 7850 2GB Sapphire Edition

RAM : 4 GB DDR3 1333MHz

Screen Res : 1280x1024

Storage : 250 GB

Operating System : Win 7 64

 

What should I do?

try -d3d in the launcher options if opengl doesn't work

Sorry, that doesn't work either.

I would try verifying the integrity of the game in steam possibly. right click the game, go to properties then Local files and then verify. Not entierly sure if that will help, but its worth a try.

I already did that.  Thanks for the help though.
