Make sure you're video card drivers and DirectX are up to date.

Also, especially if you downloaded the game through Steam, but even if you just installed it from CD's, check the game files for their integrity. To do this, open Steam, go to My Games, right click on Half Life 2, and click Properties. Go to the Local Files tab, click "Verify Integrity of game cache", and it will take a while scanning your game files.

If neither of these work, nor do Citan76's ideas, I think we'd need some more info to fix it. Or you could try http://www.steampowered.com.

Deus Ex 2

Don't get me wrong, I know Deus Ex is a much better game, and I've played it only umpteen times. But I still like Deus Ex 2 and I've played through it at least 4 times; it doesn't get enough love I think.

I lol'ed.

No one's said it so... Deus Ex.

You raid 5 hours a night for 2 months to get the best gear in the game... to have new gear released in the next patch only to do it all over again.

But but... I raid for the experience, not the gear!RandomNoob33

Sure you do. That's why everyone still raids DM, UBRS and MC. Get over yourself. MMO's all inherently blow.
