Hi guys having a slight problem that I just cant seem to figure out. Just bought the 8800 GT OC to replace my 7800. pulled the 7800 out and popped the 8800 in, but when I boot my monitor says no signal. I took it to my brothers house and put it in his computer and used the same monitor (mine) and it worked fine.
I tried finding solutions online, but the only thing i can find is "make sure you remove all the old video cards software". I did that to the best of my knowledge (unistalled the driver and removed the Nvidia folder my my C drive). But I still get the no signal when I use it. I also saw something that said "make sure your MB on board video is turned off" Sorry to say but I'm kinda Bios stupid, I looked in there and the only thing I saw was where it lets you chose the primary video card to use. It was on the PCI express option so I left it alone.
Any help I can get would be greatly appreciated, I cant wait to try out this new card.
Don't feed him that BS, PCIE 2.0 is backwards compatible.
I believe turning on the comp and waiting for the mobo to boot to windows, and then video feed will switch to your other card.
PCIE 2.0 is backwards compatible...mostly. For some reason (that nvidia refuses to acknowledge) some 8800 GT cards just do not like the older PCIE interfaces.
On my 650i, I had to RMA 2 cards before I got one that worked. They all fell victim to the "fans spin and it starts like normal, but no signal" problem. You could even hear the windows login sounds and clicking about the desktop, but saw nothing.
Yes, I know, wikipedia can't always be trusted, but it does correctly state and cite/link that revised versions of BIOSes (what's the plural for bios..?) have been released in response to this issue which shows that there really *is* something goofy. In fact,there was a post made this last december with the same motherboard, same video card, and same problem.
Anyway...before you do something drastic, check (or rather, have someone check for you) your motherboard's bios settings and make sure it's not just defaulting to your onboard video instead of the 8800 GT. If that doesn't work...you might think about trying to flash the bios of the video card (use your brother's computer for this) to make the card act like a 1.0 PCIE card. This won't really affect your performance at all, as the 8800GT isn't a strong enough card to need/use all the bandwidth that even PCIE 1.0 has. If that doesn't work, keep trying other solutions/suggestions, but you very well might have a dud of a card... =/
