My friend has an old Compaq Presario with a defective 15-pin connector built into the MB and Iím having difficulties in installing a new Graphics card on his pc.
After every boot on an XP-Home SP1 Presario, display works fine for a few seconds, then the screen is filled with small gray and white rectangular cells. Screen is okay because it works properly on another pc.
I bought an ATI Radeon 9250 PCI card, figuring that the 15-pin VGA connector on the original motherboard was defective. Once the card was put into the pci slot, the pc would not boot.
I inserted the card at home on my own pc and found that in the BIOS of my Asus P4P800 MB, you have to choose which of AGP or PCI is primary. I selected PCI and got the boot started. However, at one point in time the screen froze on the Windows logo but I noticed that the boot appeared to have completed successfully (I heard the chimes from Windows).
1. I imagine that the drivers for the 9250 graphics card should be installed while running under my current graphics card. Maybe I should also uninstall that card in the Device Manager. Then, I should change the primary from AGP to PCI in the BIOS and boot using the 9250 card. Is that how to get things running properly?
2. If thatís the way to go about it, how do I operate on the Presario where I am ďblindĒ? How could I install the 9250 drivers if thatís where the hang-up is? How could I uninstall the VGA connector in the Device Manager?
Any suggestion is welcome
