I got a new graphics card today (GTS 450) and I slotted it in, when I start it up the screen stays black, however, if I leave it for 20 seconds or so I can hear the windows start up sound.. I know my screen isnt gone because I've connected it to my laptop and it works fine. I have the Blue and White cable plugged in my monitor and my computer and still nothing, thanks.
Do you get any signs of "life" (like the BIOS Info screen etc)
If so it's probably a driver issue (did you remove the old drivers before the switch) ?
If not, there are IMHO only 5 possibilities:
#1 The card wasn't seated properly -- reseat it
#2 The card draws more power than your PSU can handle -- get a better PSU
#3 you forgot to connect the extra power cable --connect it
#4 you bend one or more pins in the video cable -- replace
#5 The card is defective -- RMA
