I have an Intel DG86WH Mobo with a P4 3.4GHz CPU. Up till recently I had 8 gig in it using the onboard video and running Windows XP Pro SP3. I was given a gift of a nVidia 7900GS and 7900GT. So throwing caution to the wind I install the GS with dual dvi ports and proceed to power up the unit. Well it wouldn't boot not even a glimmer. So I took out 2 of the gig modules and it boot, but it does not like the dvi ports since it won't display any images when I use either dvi port on the 7900GS.
Can ANYONE explain why I have to lose 4 gig to make the card run and secondly, both of the cards do not reliably show the video. I even checked the bios to make sure I had the PCI-E selected. It also seem to be really SLOW at times. I d/l'd the latest and greatest from nVidia for their drivers, but I'm losing ground here. I hope someone can tell me what I'm overlooking or what I'm doing wrong.
I'd really like to get my system back with 8 gig in preparation for Windows 7, and get the 7900's to run like a ***** ape.
I have a 320 gb SATA drive, so if any one can offer any opinions I'd be greatly appreciated. And please feel free to contact me if you need more information.
