Please uninstall everything of Nvidia using Display Driver Uninstaller and install new drivers from Nvidia. Be sure the clean install box is checked and only install the Graphics driver and the PhysX driver, you can use this tutorial to do so NVIDIA Drivers - Avoid Problems

Axe0,

I tried your latest approach regarding the reinstalling the video card drivers.

I did the following:

1. uninstalled the mentioned Display driver uninstaller.
2. download from NVIDIA the latest driver tried to install.
3. Got error that the driver install failed. (see attachment.)
4. downloaded from HP website the display driver for Nvidia
5. Failed again to install the drivers..

Trying any of the HP service pack graphics drivers downloads failed.
Any advise how to get back the Nvidia drivers on this computer

I assume the image posted covers the problem with both nvidia and HP drivers (the same problem occurs with both drivers)?

Yes with both the Nvidia drivers and HP drivers.

Eventually I had to use a restore point to get back a driver which worked.

Could you please remove Daemon tools a.s.a.p., it is often a serious BSOD issue.
