I RECENTLY bought a new VT2400 Pro 256 MB PCI Video Card. I have not a clue how to install it myself nor does my friends. I've very frustrated want to get this installation going. If anyone can help, please do.It should be a simple case of taking the side panel/cover panel of the computer tower and slotting in your new expansion card. There are many guides on the internet: http://compreviews.about.com/od/tutorials/ss/DIYPCICard.htmi've put my video card in the pci slot while the computer was off, then i plugged my monitor into the card.. i turned on the computer. its just still black.. i have no clue what to do stillI'm assuming that you are replacing the on-board (built into motherboard) video card with a PCI card. Your computer may require you to enter the BIOS setup and disable the on-board graphics. This is usually located under the 'Chipset Features Setup' options/tab You should see an option similar to "On-board graphics: Enabled". You will need to set that to disabled (+, - or enter keys to alter settings).

So first off TAKE the new graphics card out.
Plug your monitor cable into your on-board graphics port.
USE the keys F2 or Delete to enter the BIOS Setup (the POST will tell you which key). Personally I just alternate until I get there.
Enter the 'Chipset Features Setup' menu/tab.
Change the "On-board graphics: Enabled" to disabled.
Reinstall the new graphics card and you should be laughing.Thanks for the REPLY, but I've tried that too.. My computer doesn't even detect the video card either, i've uninstalled the on-board video card in the BIOS and in the device manager.Ok, then assuming this is a really old motherboard. Have you CHANGED the graphics card port from AGP to PCI? Some older motherboards need you to select which expansion bay that you are going to use. Sorry I've forgotten the correct terms for this as it has been so long since I've had to do this.Well there wasn't a AGP option but there was a On-board option. I changed the on-board option to PCI and still no luck.That card may be DOA...try it in another PC to see...
