Hi. I own a HP Pavilion with on board graphics card and PCI ONLY available slots. I use Windows XP. 512 RAM Intel Pentium 4. I recently bought a Geforce FX 5200 128 MB PCI card. When you install the card and drivers appropriately, after restart, the boot screen appears but afterwards, when XP starts, the screen is blank. Although XP and other applications ARE running, you can't see anything. I need to fix this. I've owned Geforce cards in the past, and none have ever done this on my monitor. Thanks!!
