Specs: Windows 7 x64, as above
Hello, while doing a fan upgrade,before i unplugged the power cord from computer,i accidentally unplugged my lower video card [sli system], now when in sli configuration,fsx strobes in display,change back to no sli,display is fine,have swapped cards around [gtx550ti],and also power leads to cards,monitor plugged in lower card is black screen,upper pci seems fine,also sli bridge seems good,ive tried to eliminate all possibilities,other than a pci slot failure,but device manager shows no failure notation. could lower pci have been turned off in bios,or is lower pci slot now damaged.i also reloaded latest drivers again but no change. motherboard is msi nf750-g55, amd phenom ii x 4 955 CPU 3.2hz 16.0 physical ram, all windows updates are installed.

It's PCI-express, not PCI. And I have no idea what you did to screw it up.

Were you working on the computer while it was running?
