My kids computer is an emachines model ET1331G. It has a GeForce8500GT in the PCI-e slot. This card worked fine for me for a couple years and then fine for my son for a year or two. All of a sudden it just quit working. The Graphics card still works, I've tested it, but for some reason the computer has just stopped acknowledging that it exits. I have tried everything I could think of and then scoured the internet for tips, but I've come up with nothing. I'm REALLY hoping that the pci-e port isn't just shot. Any ideas that might help?
