After much research, I decided to finally upgrade my video card from the stock Nvidia Ultra 2 to a new GeForce 7600 GT.

 

Followed the instructions exactly.

1. disabled old driver

2. installed new card (was very careful not to damage mobo)

3.  Turned on power...nothing on the screen

4.  tried installing disc with new drivers....nothing on screen

5.  reinstalled old video card...turned on power

6.  nothing on the screen...

7.  Have plugged in other monitors...nothing...

 

There is absolutely no video signal coming out of my new or old card at all.  Fans are spinning...power is on on both cards...Nothing...

 

HELP ME PLEASE!!!
