I have a desktop with windows XP. There is no picture only a no signal message. I installed another vga card but still not picture. How can I install the drivers when I can't see anything on the monitor screen?

1) Check your memory. Solution: Take out the memory and replace.
2) Monitor cable. Solution: Replace with another cable.
3) Graphic card. Solution: Take out and replace with a new or working card.
3) Power supply. Solution: Replace with a new one.
When all is very carefully checked and rechecked then restart your system. :)

Please post back if you have any more problems or questions.

Is there video built into the MB? Is it disabled? Are you plugged into the correct connection? Does your vga card have more than one connection? Have you tried the other one? Are you using a known good video cable? Are you using any adapters? Do you get video in safe mode?

Mainly because Windows isn't working in any way shape or form. You are at the bare Hardware Stage.

If you are getting a No Signal Message on the Monitor I would look at the Power Supply as the first offender. I've seen bad Power Supplies which seem to be working and will run Fan's and LED's cause this problem. I've even seen several expensive Video Cards swapped out because a Power Supply has stooped working correctly and has stopped producing the correct current of the system causing the Video Card to not generate a signal.

Normally when you have connected a Video Lead to the Video Card if it doesn't work you get a blank black screen but when you get a No Signal Message being displayed on the Monitor it's because either the Video lead isn't connected to the correct Video Outlet, The Video Lead isn't connected at all, The Video Lead is faulty and broken inside the lead somewhere so it's effectively not connected or the Power Supply has gone bad and is producing enough power to mess up the Video Card but not drive it.

I've even seen 2 people buy all new internals for their computers when this happens and then bring it to me when it doesn't work. After changing the Power Supply I've found that the Old M'Board, CPU, RAM Video Card/s work perfectly as well as the new ones which where not required.

Of course it's still best to look at the Video Lead first to check for damage things like tight bends or broken insulation on therm is a bit of a give away. Also testing the monitor on a known working system doesn't hurt one little bit either as it is possible that it is the monitor which has failed.
