Does the motherboard have the latest BIOS installed? If not, I would consider flashing to the most recent BIOS.
Also, in the BIOS make sure the onboard video is disabled, doesn't matter if it has drivers loaded or not, it could be causing a problem.
Until you get this resolved, instead of removing/inserting the VGA switch card, try shutting off the power either by using the switch on the back of your power supply (if you have one) or unplugging from wall current for a couple of minutes.
p.s. I have ci.dll on my PC, related to Microsoft Code Integrity? (Lower case i)
