Hi!!

I have the following PC for a Geforce FX 5700 Ultra 128 - AGP (Brand: Point of View [https://www.techpowerup.com/gpu-specs/geforce … -5700-ultra.c70]):

Power Supply MSI 650W 80 Plus Bronze
Pentium 4 3'4Ghz Prescott with an Artic Freezer Cooler
Motherboard: Asus P5P 800SE
Soundcard: Soundblaster 1024 Live! (SB0060)
512 MRAM
Dual Boot: Windows 98 // Windows XP

Before installing the nvidia card, I had installed an ATI 9200 128M AGP. I've uninstalled his driver with its universal uninstaller previously.

The strange problem is related with the nvidia driver version that I use. Depending on the version, it happens or not. That strange problem is when I install the driver, when windows detects the card, during the processing shows the message error:

"error loading C:\windows\system\NvCpl.dll a device attached to the system is not functioning"

Anyway, after the error, when starts windows shows a rundll error with the nvcpl.dll file (that is the control panel of nvidia). The driver is working but I can't access to the control panel.

That happens with the following versions: 56.64, 61.76, 81.98.

However If I use the versions 45.23 (modifying inf file), 53,04, the nvidia control panel loads without problem at startup, but with this versions I have problems with some games.

Sometime this problem causes some inestability like a bottleneck.

I've got a temporal fix overwritting the problematic nvcpl.dll file (56.64) with a working version (53.04) and the results is the nvidia control panel doesn't load, but at least there isn't that inestability and I can play games without problems. But.... I want my nvidia control panel so that I can use nvidia features if I want.

Has had somebody this problem? Is there a solution? I don't think the problem was the OS. I've checked the files system with its SFC tool and it's all ok.

Thanks a lot for all the help.
