Hello! I have been running Windows 7 on my 27" iMac for a few months now, and everything has been running very well. Unfortunately though, after relocating my computer desk and subsequently my computer, on startup I get a BSOD. NOrmally this wouldn't be a problem due to me still having the Mac side, but when I restarted again, I am unable to use the option key to pick which OS I want to startup in (Yes I have tried several different keyboards, but none work). I have also tried running Windows in Safe mode, but the BSOD prevents me from doing that as well. Here: http://imgur.com/iBgEUH8 is the BSOD itself, please let me know if you need any other information, I will be happy to provide it.
