I have a old HP paviliion 63XX. Its about 5 years old, 500mhz. It has no video card so I guess its on the mother board. Anyway for no reason the computer starts out fine with the windows logo looking great then when It asks to log on it switches over to a lower resolution. I try switching it to higher res but it goes back. My question is If I buy a Pci Video card will it bypass the video chip on the motherboard. Will this work. I'm planning on buying an old 64bit diamond steath card for about $10.00. Is this a good idea?
