Was wondering if anyone else has experience this? Crosshair V Formula onboard LAN causes BSOD "irql_not_less_or_equal".

Now that i finally found the reason and turned it off in the BIOS it all works flawless. Before I had trouble even getting to the logon screen.
I don't really mind as I got the big model with Thunderbolt LAN/Audio card.. (thought that was the trouble first, but worse problems if not plugged in and installed) ... but that's a major flaw imo.

I would try reinstalling the drivers, but the installer tells me I got them installed, but nothing nowhere to remove... doubt it will change anything though as I've had that problem since i got the board with several re-installs with different drivers.

Complete rig see signature (stock speed atm). My external devices are G19, G500, Logitech USB Headset (p'n'p), Amp via speaker out. Not much to create a conflict there unless its the Logitech drivers somehow.
