Hello,
I had been having some monitor distortion issues on my Dell XPS m1210 so yesterday I downloaded the nVidia GeForce Go 7400 from the Dell support website.  Now I have even bigger issues.  Upon restarting, I was left with a black screen and am not able to do anything.  No Dell screen to try launching the F8 or F12 tools.  The hard drive light is on and the notebook sounds ok but the screen is blank. 

I tried to get to the diagnostic tools by using the CD and no luck that route either.  I also read that I could try reinstalling Vista.  Is that my only other option at this point?  

Any other suggestions? 

Thanks
