Sorry for not responding in so long, I've been away for memorial day weekend. I didn't run any of the updates yet so no worries there.. and Yes I have an earth watts 500W power supply. I don't have the make/model right now because I'm at work but I can post it later today.
As for the other cards in the computer, I also have a sound card installed into the bottom PCI slot. I could switch the sound card to the more "middle" PCI slot and try it, but with the sound card in that slot I wont be able to put the 8800 GTS into the PCI-E slot (thanks gateway for giving me no room to work with). But to answer your question, yes there was the 8800 in the PCI-E and a sound card in one of the PCI slots.
If you want to see what my MB looks like you can go here and look right on the first page..
try the sound card in the middle slot if you like but i don't feel that is the problem , i will do a bit more searching see if i can find a solution
