Have you tried a different card in that pci-e slot? Do you have a different slot to test the 9800gt in on your motherboard? Re-seating (take it out and put it back in a few times to clean up the contact points) the card may work. It could be the card or the motherboard.
Check for blown or bulging capacitors on the video card and the motherboard if you have any bulging or blown caps, consider replacing those parts example here: https://www.google.com/search?q=blown+or+bulging+capacitors+motherboard&source=lnms&tbm=isch&sa=X&ei=708rU9HFEoP1qgH4zIC4AQ&ved=0CAgQ_AUoAg&biw=825&bih=414
If you can find a different video card to test with, that would be what I would try first after re-seating the card.

In addition to zingo156's excellent advice, your BIOS may be one where you have to disable onboard video.

i have one of those 9800gt cards. it is sensitive about recovering from sleep/hibernation/standby etc. it probably has a 6 pin connector on it. make sure it is plugged in.
mine started acting funny one time. i just unseated it and uninstalled the drivers and ran on the onboard for a couple of days and then reinstalled it. and all was fine again.
those cards usually need about 100w and if the power supply isn't around 450 watts or better, the card may go black like what you describe.
also, 9800gt are notoriously hot because of the fan exhaust configuration and without fan speed adjustment (msi afterburner or rivatuner) on them, will idle around 60 c. over time, that kind of consistent heat will damage components on the board.
if you can try the card in a different machine to see if it is absolutely black, that will deduct a few variables.
