I just got a brand new XFX GeForce FX 5200 128MB DDR 8X AGP vidio card. I disabled onboard vidio, shutdown pc, installed card, started pc. My monitor will not even light up (hooked up to vidio card or onboard outputs) The power light on the monitor stays yellow doesn't turn green. The yellow hdd light on my pc comes on hard with the card installed. If I remove the card and enable onboard vidio, everything goes back to normal. Defective vidio card? Thanks.
