Halo Graphical Glitch?

A couple possibilities:

Did you uninstall your old graphics drivers before installing new ones?

Have you run DXDiag yet and run its DirectDraw & Direct3D tests?

Are any other DirectX apps experiencing problems?

Your description was a little vague, but did this error occur while you were playing for an extended period or just one day when you started it up?

Have you tried reseating your video card (yank, blow, plug & push)?

I couldn't tell what you were answering in #4, but if you were reffering to my suggestion to reseat the video card that really doesn't have anything to do with moving your PC. A lot of parts come lose or experience bad connections over time.

For example, a month ago I installed a brand new video card in my system and a few days later my system would occasionaly boot without video. I pulled the card out to try reseating and discovered a ball of fuzz on the cards connectors. Removing that solved my random errors and my card has done great since. (Thank goodness!)

My suggestion to you was simply to remove the card and insert it again as a lot of random errors are solved this way.

It's always good practice to uninstall old drivers before installing new ones. NVidia even recommends that you never do otherwise.

Have you tried reinstalling Halo or patching it recently?

I just installed Halo last night. Things go fine till you load up a game. Play for 15 seconds-FREEZE_ for 5 seconds. Play for 10 seconds-FREEZE- for 5 seconds. With an A64 and a 6800-O/C I have no problems in any other games. Halo seems to hate Nvidia cards with anti-aliasing turned on. I'll try some different drivers tonite.

Thanks for the tip, krisz.

Hmm well did you try to search on google to see if someone else had this kind of problem as well with the same setup as yours ?
