video adapter

Is ur hard drive recognised? It may not be formateed properly. Is the hard drive system formatted? Does the system beep when booting?
If there are no extra beeps - then you need to format your hard drive.

If you get no video, and no beep codes when you first boot the computer, I would suspect the CPU, MB, or Power supply.

It also could be that the CMOS reset jumper is in the clear position.
Double check all jumpers and dip switches on the MB.

A weak CMOS back up battery could also create strange problems.

How do you know that the power supply is good?
There are at least 4 different sections of the power supply. Just because the fan runs, or your drives spin up does not prove that their is no power supply problem.

Double check that the power supply connectors are seated fully into the MB.
Remove and re-seat the RAM modules. Check for corrosion on the pins. Very important if the MB uses SIMMs.
Verify that the CPU socket latch is closed tight.

Next, remove all plug in cards except the video card, and disconnect the drives from the MB.
If you now get the boot screen, add the other devices back in one at a time until you find the culprit.

Otherwise, it's time to start swapping out the main components.
If you swap in known good RAM, CPU, and power supply, then it must be the MB.

Hi,

The next thing I'd try is putting your video card in another machine and see if that works.

It sounds like a faulty video card if you've swapped another known good one in and it works...

Cheers,

What kind of video card is it? I just installed 2 new Compaqs for a customer. They had no built-in video, and were ordered with Matrox dual-head video cards from Compaq. I had video problems with the second one-Monitor came on once, then looked like it was bad video. Could get the monitor to come back by switching monitors, but that would only work for one boot. Swapped cards between 2 systems & problem remained at the original PC, so I had Compaq replace the motherboard. STILL had the same problem, it turned out to be some sort of incompatibility with the customers old MAG Innovision monitors, connected a newer Acer monitor and it was fine.

1) Maybe your motherboard does not support this video adapter.
2) It is loose in the slot. Fasten it.
3) Upgrade the driver or find a suitable one. Sometimes the motherboard ONLY support a certain driver for a video adapter. Or it will become unstable.

what type of video card is it? AGP, PCI??
most newer cards w/32mb RAM & up require alot of power, if your power supply is only 150~200 watts, it may not be able to power the card. try a 300W power supply.
Also, does the AGP slot support the type of card i.e. 2x/4x/AGP Pro?
