All of a sudden, my videocard (GTX670) is not running in PCI-E 3.0 16x mode. Instead, it varies. Sometimes it shows as PCI-E 1.1 4x mode, or PCI-E 1.1 16x mode.
I even swapped it out for my backup GTX280 which is a 2.0 card and it also shows as a PCI-E 1.1 card. The cards are being installed in PCI-E Slot 1 port which is the closest to the CPU and it's the one it has always been in.
Another odd thing is that no matter what I do in the BIOS, I cannot disable the CPU's iGPU. I remember not showing up in the BIOS but now options for it such as voltage and frequency have appeared in the BIOS for the iGPU and I did NOT enable. It appeared on it's own. As a matter of fact, when I rebooted, I noticed Windows recognizing new hardware and now the iGPU appears as an installed videocard in my system. I had never done that because I had disabled it from the day I build this computer.
In the BIOS, I have PCI-E as the primary display and iGPU multi-monitor support is disabled, but the iGPU cannot be disabled.
Does this sound like a mobo issue? Thanks for any help.
