Just purchased a Diamond Viper V770 and running on a 503+ with Bios\nJe4330, trying to stretch the motherboard's life. The video sucks,\nbars running across the screen from text and open windows and the\nvideo is fuzzy. The base chipset is the nvidia tnt2, which many\nposters here said works great. I don't believe upgrading to the\nJe4333b2 for an AT power supply will help but maybe. The bios is\ncurrently set to AGP2x, just looking for ideas. The card is used,\npurchased from Ebay. Also, having a problem with finding an updated\ndriver on the nvidia website, they seem to be pushing Geforce drivers\nand nothing earlier. Any help will be greatly appreciated and this\nmotherboard and this message board have been fun. Also running VIA 4\nin 1 chipset driver version 5.0+. If I make this video card work,\nnext step is a Promise ATA 100 controller card and new harddrive.\nthanks again for any help.
