I run XP home, computer was working FINE, no problems, 1 day it would not start. replaced power supply, and it now turns on, fans spin, i hear HD spinning, mother board connection in place BUT i have no video signal now....is there a monitor connection on the motherboard from the power supply that i missed? I dont see anything....what else could it possible be??? i tried 2 different monitors and same result...

There may be a power connector to the video card depending on the video card.

What is the brand and model of the new video card?

This may be a silly question, but have you made sure that your monitor connects to your PC correctly? Generally there is only one place to connect your monitor, but sometimes there are two (if, for example, you have an integrated card and an expansion card). Try connecting your monitor to every place it can be connected to rule out this simple mistake.

If the problem persists don't worry about your PSU, worry about your mobo instead. Even if you have a crappy card and bad drivers, you should be able to at least boot into safe-mode. If you can't, you very well may have a serious problem... sorry!

its a factory installed one and i have an additional one that i installed over 1 year ago...i have NEVER had video problems before, i tried both video adaptors and both give me the "no video signal"

again.....this ONLY happened AFTER i installed the new power supply, could it be it doesnt have enough power to juice up the monitors?? the factory was 250W and I purchased the same one...

the HD spins, the cd-rom opens, and its connected to the mobo properly....

This could be, the new PSU you bought could not give off enough voltage but be the same wattage.. If you dont mind me asking, why did you buy the same PSU?
