i'm running a dell xps 410 with vista home ultimate.

i was switching out monitors when i went to the "display properties" and changed the refresh rate [from 75 to 85]. the screen went black, and never came back. my suspicion is i somehow killed the graphics card [nvidia geforce 8500] because when the monitor's connected i get a "loss of signal" box on-screen, rather than the monitor going to sleep. when the computer is on the card's fan spins; it's getting power. so it's doing something. or nothing, actually. this happens regardless of which monitor i connect. i'm using the digital video connector.

You most likely selected an unsupported refresh rate.

-Restart the PC and tap F8 during boot.

-Once at the Advanced Options menu select Enable low resolution video (640x480)

-If you are able to login to Windows you should be able to lower the resolution.

i can't; the monitor stays blank with f8, without f8, or thinking about f8 [or any other key combo]. i also tried a system restore disc...nothing. the monitor's not the problem, as i hooked it up to another machine and presto! i also switched out the video card for a new one.
