Crash / freeze when entering controler setup menu

I'm posting this for one of my regulars because it bugs me that he's having these issues. I'm almost certain there's an easy explanation but it's eluding us both.

Anyway... I've run him through all the usual suspects... the repair, the delete... the DCS folder in saved games... gone through that a few times. He just did a full wipe of his drive and is still getting the issue. His specs as follows:

i5 3570k ivy(4.5 OC), ASUS Maximus V Formula, 16gb GSkill RipJaws 2133mhz, 2xEVGA SuperClocked+ GTX 680 in SLI, 2x Kingston HyperX 240GB SSD's(1 for OS, 1 for Games), Corsair H100 Watercooler,ASUS Xonar Phoebus SC, Windows 7 x64, Razer BlackShark BF3 Headset. CoolerMaster Cosmos II, XFX Pro 1250w. Samsung 46" LED TV(7100 series) ASUS VG278HE 27"144Hz, Saitek Pro Flight pedals, Thrustmaster HOTAS Warthog, Razer Nostromo, Razer Naga, Razer Deathstalker Ultimate.

As soon as he goes into the control options- his computer freezes and he needs to restart. I'm trying to harvest a couple logs off him but not sure if it'll help.
