Hi, im stuck in a very strange predicament involving my computers graphics processing.

I have a geforce 6800 GT OC in an amd athalon 2900+ with 768mb of ram. Awhile (several months) back i started getting video tearing on my screen and static like lines appear. It never used to be that bad just annoying but recently it gets so bad that when i play CS: Source the graphics just freeze and I have to reboot.

I was told by an nvidia customer support guy that the problem could be one of three things.

1) The power supply is bad: I have had this problem through 2 power supplies and doubt they were both bad

2) The video card is bad: I put it in my fathers p4 and it works fine

3) The socket on the motherboard is bad: I swapped my fathers 5200 into my computer and it worked fine.

Also I have reformatted and tried three sets of drivers for the 6800.

It seems to be some sort of problem when i plug the power into the 6800 directly (it has its own power slot), the 5200 however does not need its own power and works fine?

I have no idea what is causing this and can't afford at the moment to just pickup a barebones amd 64 and put my hd's ram and video into that. Thanks for any help - Will

Hi Will, welcome to the PCHF.

First thing i would like to check - is to make sure youre using "V-sync"
This limits the amount of FPS you get match your monitors vertical refresh rate - most LCDs sit on 60hrz.

You can check this in Display Properties -> Settings -> Advanced -> Geforce 6800 GT -> Performance Options

im pretty sure i set the vsync right, ill check it tomorrow though as my PC is in pieces right now. one more thing i thought i'd add, with no drivers, and no hardware acceleration but still running through my 6800, there is no static.

that is odd...


try the latest drivers from nVIDIA Geforce 8800 8600 7950 7900 7600 GT GTX ATi Radeon x1950 x1900 x1800 1600 XT Pro - Guru of 3D: PC Hardware Reviews

might help you out a bt...try the modified ones as well - they're sometimes better for performance.
