I have just bought an 8800gt xfx as my old 6600gt died. But the trouble is, the system won't post or boot with this new card in. I should probably point out that the old card was AGP and the new card is PCI-E. Does any one have a similar set up or have any idea why this may not be working?
I posted this previously but gave the wrong board details (half asleep).
you probably have to go into BIOS and change your primary video device from AGP to PCI-E. Hopefully you have an adequate power supply too or else you'll have other problems. Hope this helps
