A friend of mine is selling his old Alien Ware tower to me. I what the system, but we can figure out why the video is boxy and scramble on boot up and in bios screen. I try two other different graphic cards, and the system will not boot up into bios. The system just sit there and does nothing. I sitting here pulling my hair out trying to figure out what the problem is. Any idea what causing the problem? A7N8X-E motherboard with AMD Athlon XP 2600+ with 2 GB of DDR333 ram. Geforce 6300 OC graphic 8x card.
