Help!!! LeadTek A280 causing probs

Hi,

The LeadTek A280(le) THL MYVIVO graphic card installed into ASUS P4S8X motherboard is causing me alot of problem.

I have the latest SIS agp 1.3 driver installed on my comp and have set the bios' agp to 8x as well as flashing my MB bios to the latest v1.005 (i think tat wat it called). The graphics card would work fine without any problem (though the vga controller in my device manager is in exclaimation). However, i would not be able to play 3D games, eg counter-strike in open-gl mode.

So i decided to download and install the latest LeadTek A280 driver (A280 series). Anyway, i downloaded latest nvidia G4 driver for winxp as well.

After installing the LeadTek driver(A280 series) together with the nvidia G4 driver, my comp would hang when i start playing any 3D games and even in windows, my screen would keep fickering.

I installed all the latest driver but still the graphic card is not working. Wat the hell is wrong???

BTW i'm using an 15 inch Philips LCD.

Can anyone pls help me....
