I installed the Pre-release Driver for my NVIDIA 7600 GT video card, and restarted my computer. It said it had successfully installed, but i cannot seem to be able to display the native resolution of 1440 x 990 for my 19 inch widescreen monitor and on Device manager I get the following message -

This device cannot find enough free resources that it can use. (Code 12)
If you want to use this device, you will need to disable one of the other devices on this system.

Could someone please help me to find a way how to solve this issue.

These are my computer and OS specs,

Windows 7 RC build 7100 (dual booted with) Windows XP proffesional
2gb RAM
256 Mb Nvidia 7600Gt graphics card
Intel pentium D ( i cant remember which model i have, but it is 2.8 GHZ)

SOMEONE PLEASE PLEASE PLEASE HELP ME
Thankyou
