PCI Video card does not work

[rsheshappa]

Hi,

I am new to this problem so my explanation may be incomplete but I appreciate your help.

I have eMachine computer running Windows XP Home. This came with onboard video. I have bought a nVidia GE Force Video card and have installed in the computer.

This new card works only in safe mode. If I go in normal mode the screen is blank. At that point If connect it to onboard video it seems to work fine.

I thought it might be a driver problem so I tried downloaded the dirver from nVidia. When I run that I get the following error.

'NTVDM cpu has encountered an illegal instruction.....'.

Is there anyting I can do to solve this problem?

Thanks

3 steps starting without the pci card out of the machine:
1) in bios set primary display to PCI
2) in WinXP device manager, right click on onboard graphics device & select "disable"
3) shutdown machine & install pci card
