Hi,
I tried replacing my existing ASUS Radeon 9250 128Mb AGP graphics card with a Sapphire ATI Radeon 9550 256Mb AGP card purchaed on Ebay recently (needed DirectX 9 support for a game that my son bought). I un-installed the 9250 drivers in Device Manager, powered off the PC (Compaq EVO D510 CMT, Pentium 4, 2.4 GHz, Intel 845G Chipset, 1.5 Gb PC2100 DDR Ram, AGP 4x, 2x IDE HDD 80 Gb & 40 Gb, DVD-RW & CD-RW, 220W PSU, Windows XP Home w\- SP2) changed over the graphics cards and powered the PC back up - the cooling fan on the card ran. When the start-up got to the first Windows XP screen the blue moving dots were garbled. From then on the display was garbled with bars down the screen and very difficult to read. However, I could see in the clutter that the desktop had appeared and the "Detected New Hardware" had come up. I directed the wizard to the folder where the display driver was located and it started copying files. However, at the end it said it encountered a problem and that the hardware could not be installed and "Access denied" - after a few minutes it locked up.
Have I gotten a lemon or can someone suggest a solution?
Thanks
