Not to beat a dead horse, but this is bothering me. Does anyone *not* have this problem show up in the device manager:
yellow exclamation points by the following entries:
"PCI Device"
"Intel(R) 5000 Series Chipset PCI Express x4 Port 3 - 25E3"
"Intel(R) 5000 Series Chipset PCI Express x4 Port 5 - 25E5"
"Intel(R) 5000 Series Chipset PCI Express x4 Port 6 - 25E6"
"Intel(R) 5000 Series Chipset PCI Express x4 Port 7 - 25E7"
If you're new to Windows, you can access the device manager by right-clicking on "My Computer" in the start menu, selecting "Manage", and then selecting "Device Manager" in the left-hand pane.
The exclamation points indicate that devices are not functioning--in this case due to lack of drivers.
I tried to install them manually by pointing to the unzipped Intel inf folder, and each port seemed to accept them, saying they wouldn't take effect until Windows restarted. But upon restart the problem was still there.
