missing 'display' features in control panel

Yesterday I tried to uninstall my previous graphics card (NVIDIA GeForce 8500) to install a new one, Saphire Radeon X1650. However, in doing so I accidentally uninstalled some motherboard drivers as that is also NVIDIA. I have now reinstalled all the drivers on the motherboard CD BUT it is coming up with error messages when loading:

Initially it is saying "fail to load nvcpl.dll", and then stating that there is a problem with SW20.exe and it must close. I tried uninstalling and reinstalling the graphics card, reinstalling the motherboard drivers again and eventually tried the Windows XP recovery disc. However during the recovery it stated it could not copy the apr9t8dk.sys file and had to abort the recovery. Does anyone have any idea what I've done?!

My motherboard is the ASUS M2N4-SLI. The main problem is that I cannot get into the 'display' folder in the control panel and thus cannot set up my new graphics card properly. Hope someone can help!

More than 2.0GB RAM?

If so, downsize during restore. Also duplicate the restore CD just in case it's not reading proper. Always a good idea to have duplicates of CDs you can't lose.

uninstall your display adapter in device manager

In reply to: missing 'display' features in control panel

and put the 8500 back in. when you reboot don't allow windows to add drivers for it.

get the latest mobo drivers, install those and reboot.

open Add or Remove Programs and choose 'NVIDIA drivers'. Select 'Remove only the following', check NVIDIA Display Driver and click [Remove] and shutdown.

swap the video cards and reboot. don't allow windows to add drivers for it. now install the catalyst drivers.

Device Manager does not show Display Adapter for NVidia

In reply to: missing 'display' features in control panel

I just fixed this problem on two machines. (Actually, one physical machine with two hard disks, each of which can boot Windows.) The problem suddenly appeared with two different NVidia AGP cards, the GeForce MX4000 (64Mb) and MX440 (32Mb).

I have a Soyo Motherboard SY-P4VGA with VIA Technology chips. I'm running WinXP Home with Service Packs 2 and 3.

The problem turned out to be the VIA CPU to AGP Controller driver, a 2003 version from VIA Technologies. When I rolled back the driver to the Microsoft version suddenly Display Adapter was back. These are the ones that work:

Ver. 5.2.2600.5512 date 7/1/2001

*** Microsoft sends the VIA Technologies driver as an Automatic Update. ***

To access this:

Control Panel -> System -> Device Manager -> System devices ->
VIA CPU to AGP Controller
Right-click -> Properties, Select Driver Tab
