Are you connecting it to the video card or the mobo? I have a connector for monitors on my mobo, and a DVI and VGA on my 7800. Doesnt work on the mobo, only the video card for me (also using a dvi-vga adapter, running dual monitor).
There are no drivers that have to installed other than the normal video card drivers, even these will not be required to get a signal for boot-up.
Have you used the DVI adaptor that came with that card? I tried to use an adaptor that came with a different card on an 8800 and it would not work, I wasn't aware of any differences but apparently there are some.
There also should not be any difference which port you connect to on the card, they both should work pretty much the same.
Umm... is the card plugged in? To the PSU? Sorry I had to ask. I know that my old GeForce 6600 would tell you if it wasn't plugged in, but some might not. If not, you may have to consider the possibilty that the card is a lemon.
You see the bios information but do not see windows once it loads? Are we sure windows is loading do you hear the noise through the speakers? You should also start a support ticket at www.xfxforce.com and PM me the ticket number. Have you tried using another DVI-VGA adapter? Is the monitor set for VGA as the input?
Support Tickets are our way of keeping up with the situation. Sometimes it takes more then a one word answer. Questions have to be asked in order for a solution to be formed. That was the single most ignorant comment I have read today.
