I built a 2000XP today and here is my problem. I am using an Asus board with an onboard Geforce 2 GPU and when I use it, my video is fine. When I plug in my VisionTek G4 TI 4200 I got alot of horizontal lines on my screen that is different colors, so bad it is hard to see the screen. this is a fairly new card so I was wondering if my 300W PSU isn`t enough to power it, am I right? Any help would be apreciated.
