So I want to install an R7 240 into an old hp which is running a Pentium D 805 and ATI Radeon Xpress 200 graphics which is part of the motherboard. I put the R7 240 in, hooked it up to a monitor using a DVI to VGA adapter and booted up windows XP media center, I downloaded this driver : http://support.amd.com/en-us/download/desktop?os=Windows%20XP%20Media%20Center%20Edition and ran it. After I restarted the screen was still a low resolution and there was no Amd ccc and it gpu was not recognized, I realised I didnt uninstall the ati Radeon Xpress 200 graphics so I uninstalled everything with ati in its name in the change/remove programs in the control panel. After a reboot there was no difference and no gpu displayed in msi afterburner. Am I doing something wrong?
