Can't see most things in games

[JooK]

This isn't really a Hl2 question, but this is the game I want to play in general.

Ok, I have a bougth version of HL2 and it installed fine without any problems. But when I go to play it, all the enemies and models don't show up on my screen. Even in the main menu, I can't see the guards walking around and I only see a floating light blinking red and I guess thats supposed to be that thing that alerts the guards of your presence / blinds you. I don't see the poles in the ground, and when I start a new game, I don't see that guy with the brif case or the damn seats in the train. I can see the buildings / structures / floor around me though.

Specs

AMD 64 3200+ Xp home
1gb PC3200 ram
200gb HD
Intergrated 128 mb graphics.
e-Geforce 6800 128mb 8x agp - replaced the integrated graphics

I THINK I have the right Nvidia drivers. When I check in device manager, it says the 6800 is working properly, and the driver is 7.7.7.7 (even though I downloaded and installed the 77.77 drivers from the Nvidia site) .

This problem applys to other games too (IGI 2). But this problem does not occure when I play Serious Sam. Currently, my computer case is open, and the card/PSU seems to be in correctly.

Did you Uninstall the old drivers? Drivercleaner

did u unistall the drivers to the intigrated card and disable it through hardware settings

When I go into device manager, there is no intergrated card. All it says under Display adapters is "Nvidia Geforce 6800". I;m starting to think it is that integrated video though, because my gf6 worked on my older computer.

Also, I invented a new wall hack for BF2!!! I am plainly shooting a wall, but you can see the trees and shrubs on the other side! lol, j/k. But seriously though I'm playing with the latest drivers 77.77 and playing with earlier drivers didn't help either.
