I disconnected all my extra monitors and reinstalled a third time. Seemed to help.

I haven't raced in a while but I upgraded to S3 and installed the latest update the other day. I was about to try it with my new Oculus Rift but as soon as I click the icon the PC restarts (clean install of LFS -> NO CFG files or anything). Tried again with the same result.

All other sims work (iRacing, Assetto Corsa, Project Cars).

Help anyone?
