Is the card fully/properly seated?

by seanferd In reply to No video, but Desktop pow ...

Is the monitor cable connected properly to the monitor and correct port? (Like if there was integrated video as well.)

Did you get any video drivers installed? can you boot into safe mode?

You might want to tell us the make and model of the system and mother board, as well as that of the card, and what operating system and service packs you have installed.

Well it would help no end if you where to post the Hardware Details here

Trivial Unimportant things like the Make and Model of the M'Board and Video Card would be a good starting point as some Video Cards are Incompatible with the M'Boards Chip Sets. If we don't know what you have we can not warn you of Incompatibilities.

Also the Make & Model of the computer would help no end if it is an Off the Shelf System as it is more than likely that a Dead Power Supply has destroyed the M'Board, CPU and RAM some brands like E Machines are known to do this with alarming regularity.

Also as the Power Supply has been replaced have you made sure that you actually plugged everything back in? The newer M'Boards have a Supplementary 12 V DC Plug and if this remains unconnected there is no voltage available to power the Video Card so it appears not to work.

What if anything at all is appearing on the Monitors Screen. Even a No Signal Message tells you something.

Something else to try

by Jacky Howe In reply to No video, but Desktop pow ...

Does the System have on-board Video. If it does try connecting to it. Plug the Monitor into a known working power outlet. Test it with a radio or a lamp. Check the cables for bent or broken pins.
Start by turninig off the power to the PC from the wall and remove the power lead from the PC. Remembering to ground yourself by getting into a position that will allow you to access the components without moving your feet and putting the back of your hand on the Power Supply Unit (PSU) after you have removed the PC's Cover. By not taking this precaution it is possible that you could inadvertantly cause damage to the PC from an electrostatic discharge. Disconnect the 20-24 pin power connector from the motherboard. Reinsert the 20-24 pin power connector to the motherboard. Remove the Video Card and clean the golden edge of the card with a soft rubber eraser, remembering not to touch the golden edge. Reinsert the card and see what happens. The faulty (PSU) may have damaged the PCI slot.
