Today I bought a Geforce 6200 graphics card because my computer met all the requirements. When I installed in my computer and turned the power on there was a beeping noise and the computer screen was black. I don't know what I did wrong. My guess is my computer is not compatible or somethings up with the card or dirvers, I really don't know since this is my first time installing a graphics card. The requirements of this graphics card is: petium 4/III/II/celeron, AMD K6/Athlon. An Agp 8x or 4x motherboard. 256mb of memory at least. windows xp. a minimum of 250w power supply. I have a AMD Sempron 3100+ 1.8ghz, an agp slot 3.0, 8x. a 250watt power supply. and windows xp. If you could help me out in any way I'll be very greatful. Thank you for your time.
