Humm that's troubling for sure. I would try alternating the BIOS setting for Plug & Play OS and see if having the Bios assign the IRQ vs the OS assigning it helps. This solved my networking issues of randomly waking up from sleep with network teaming enabled. I had to deleted all drivers..remove hardware from device manager, reboot with plug and play OS no before I could reinstall the networking drivers properly.

Also...I thought I saw another poster in this thread who was using a RAID controller card on the 790i in his sig...I'll have a look through the sigs and see if I can ID him, maybe he could help.
