I've got similar problem like http://www.fixya.com/support/t2244032-black_screen_agp_video_card_update.
Except I got PCI card (GeForce 8400 GS). Running Windows 7. Downloaded latest drivers from EVGA site and they are apparently working correctly. However, I just get black screen, although I set BIOS to 'Auto' and Video DAC Snoop to 'on'.
I have a 650W PSU, I uninstalled drivers for onboard video card. Power is present as I can see illumination in the background.
Tried it also on Dimension 3100 running XP pro SP3 - same thing. Called EVGA, they said it's a HW problem and replaced the card. I still have same problem. What in the world am I doing wrong???

Re: Black screen with new PCI video card
We can troubleshoot it and repair it. There is no doubt of that in my mind. But now that they admitted their fault, this is the time to make them fix your computer. If everyone would do the same thing the stealing of the customer's money will be decreased by a large measure. Again, if you want us to work on it, we are ready able and willing. But the truth must be told..... Thank you for your considering us and your choice to work with our service. My name is Constantin (arzconst is an internal nickname used with the Fixya.com).

That could be the video chip if have on board video. I don't know if you have an AGP or PCI slot to add a new video card. The Agp is brown color and always is just one. The PCI are white, and you can have 2, 3 or 4. You can buy some cheap video cards on ebay.
Your Intel D850MV motherboard uses an AGP video card. There is no onboard video (built into the motherboard). Before replacing the video card try swapping out your monitor with another. Check for display. When the system is powered on can you hear the internals running?
If the swapped out monitor does not show display you'll have to replace the AGP video card.
The Intel D850MV motherboard only supports AGP cards that run at 1.5volts only & can run at 2x or 4x speed.
Intel shows the difference between compatible 1.5v AGP card connector & the 3.3v non compatible video card connector. Click on the Intel link to see this;
This next link shows a compatible AGP video card that will replace your old card;
Thanks for using fixya
AGP driving control If you get it wrong, the graphics card won't boot, and you'll be left with a black screen. The only way to remedy this is to temporarily use an old PCI graphics card, change the driving control setting, and then reboot
sounds like 8x agp. go to new egg.com. good deals on vid cards there. unfortunately for you the agp doesent get into the higher end video cards. nor does the standard pci. the transfer rates just aren't fast enough. but unless you are doing serious gaming either pci or agp will give you about the same frame rates.
Try uninstalling the driver and all nvidia products, download the latest driver from nvidia's website.
If that doesnt work, then your motherboard is the problem. Older AGP motherboards tend to have problems witht eh geforce 6200/6600 series cards, I recommend updating those drivers and seeing what the deal is.
