Hmm, something is holding up your USB. I recommend turning on Link Removed as instructed, then restart and let it crash the system a couple of times, then send us the resulting crashdumps. If it causes a boot loop, tap F8 before Windows logo to go to Safe Mode, then disable Driver Verifier there by opening it again and selecting Delete existing settings then press Finish.
What devices do you have hooked up via USB? Do you also use a USB hub of any kind, including any on the monitor?
