I have power but no video

What video card are you trying to use?
Jumper of charging = Power cable?

If you mean you need a 6 pin or 8 pin PCI-e Graphics power connector, these are available from any good computer or electronics store. They connect to spare SATA or 4 pin peripheral power cables from your computer's powersupply. Make sure you know which power cables you have available in the machine, as well as the requirements of the video card (1 or 2 cables, 6 pin or 8 pin), before you choose your PCI-eG power cable.

if computer powers up I would suggest looking over your work again with the video card. I would bet loose power cable to video card

TRY THIS

1. • 1 Turn the TV off with the front-mounted power button, not the remote. Unplug the TV's power cord from the wall outlet. Let an hour pass before plugging the cord back into the wall outlet. Turn the TV back on with the front-mounted power button and wait until it has fully restarted. Bring up a TV channel to see if the image being presented on the LCD screen is no longer flickering. A momentary power surge can cause the circuitry inside the LG-brand LCD TV to function erratically.
     
   • 2 Unplug the video cable from the video connection on the back or side panel of the LG TV. If more than one video cable is connected to the TV, disconnect all of them. Disconnect the other end of the video cable from the video source device that it's attached to -- a DVD or Blu-ray player, or a satellite receiver or cable box. Blow off the connections on the video source device and on the back or side panel of the TV with bursts of compressed air. Reinsert one end of the video cable into the video source device and the other end into the video input that it was connected to. Turn the TV back on with is remote to see if the picture is now free of flickering. A loose or partially connected video cable can cause the LCD TV's screen to flicker when presenting an image.
     
   • 3 Turn the TV off and unplug its power cord from the wall outlet. Place a power conditioner next to the wall outlet. Plug the power conditioner's power cord into the wall outlet. Plug the TV's power cord into one of the AC sockets on the power conditioner. Turn the power conditioner on. Turn the TV on to see if the picture is now free of flickering. The RF signals in the electric line that the LG TV is drawing power from can cause flicking through interference patterns being generated.
     

You need to set the Bios to default to your video card and not your on-board video or disable the on-board video in the Bios..

Phase 1
After power button pressed, computer will detect 5 components :
1. Power supply - OK (enough power)
2. Main-board - OK
3. Processor - OK
4. Memory - OK
5. Video Card / VGA - OK
== beep sound .. (1 time) or on the monitor, display appears BIOS ==

The characteristics of damage to power supply
1. Power supply fan does not spin

Video power supply fan not spinning

If the power supply fan is not spinning, the possible cause of damage to power supply. Solution, replace the power supply.

How to check the damage to power supply
2. Power supply is weak (resulting voltage power supply can not turn on the computer or the voltage is less)
The characteristics of damage to the processor

Normal fan without processor
Normal fan with processor


Based on experience, the possibility of damage processors is very small. To check for damage to the processor, install the processor to another computer (for comparison).


The characteristics of main-board damage
Because the new main-board, so the possibility of the main-board damage, very small. The characteristics of damage to the main-board, when the power button is pressed
1. Power supply fan not spinning
2. Processor fan is not spinning
3. Casing lamp is not lit
4. Main-board lamp does not light


The characteristics of the memory damage or dirty memory
1. The characteristics of normal memory, but installation is not correct or dirty

When the computer is turned on, the sound


Solution



Picture a
Release Memory

Picture b
Clean the memory slots with a brush

Picture c
Clean the gold layer memory with a pencil eraser

Picture d
Reinstall the memory correctly

The characteristics of damage to video cards


Solution, remove the video card, clean the gold layer with a pencil eraser.

I hope this information helps.

There are two types of video cards, Ones which power themselves for the Slot and other high end ones need to be powered from the supply. Most video cards are provided with a cable like this one. You will need this cable in order to properly connect your video card to the power supply.

Hope this solves your problem.

try differant video card jim

From what I gather, your computer has a PCIe v1.0 slot for a video card upgrade and comes with intel on-board video. So you will need a PCIe 2.0 video card (v1.0 are no longer available and 2.0 are backwards compatible)

I assume, like most PC's, yours has a 350-450 Watt Power Supply. Check your power supply to be sure, you just can't put any video card, you are limited to the available power from the power supply. If you want a top of the line video card for gaming you will need a more powerful power supply. If all you need is better performance and better video quality (DVI/HDMI) then any sub $100 dollars card will do.

I cannot emphasize enough, check your power supply wattage capacity and the watts required by the new card before buying.

Also, do you have additional power connection from the power supply for the new card? most cards, not all, require a 6-pin PCIe power connector.

I would reinstall your OS.

There are a couple things that you need to look at. The first is your power supply. I've had computers seeming to run fine with no video. Turned out to be bad power supplies.
Does your video card require a power connection? Many high-end video cards need an external power connection. If the card has a power connection, use it.
Have you gone in and checked the cmos settings? What does it say (if anything) for the default video?
Now remove all connections to drives (hard drive and CD and try for video. Try it.
Next, if possible, swap out memory.
After you've tried everything (including maybe burning incense), time to try a new motherboard.
