Hi guys, I've installed windows 8.1 with bootcamp, and I've never had any problems. Then I installed battlefield 4. Anytime I'm playing some error happens, but today I got a bluescreem and my windows never came back. The task bar doesn't stop flickering and a error (something like "DDE Server Window: explorer.exe error") comes and never leave. I've tried a lot of things, included sfc /scannow and dism /online /cleanup-image /restorehealth, but nothing. Please help! Thanks. EDIT: My system is a 12-core MacPro 2012 (MacPro5,1) with 24gb of ram.
