Hello guys, I am new to the forum and having iMac problems. First off it's a 27in 2011 model with a 250gb ssd drive and a 1tb drive. I have Windows 7 installed on both drives and Mac OS also installed on the 1tb drive. It has been working fine until 3 days ago I was watching a video on IGN's website and then all a sudden it went all white and froze. Now it will not load any OS, it acts like it will load up but on windows the screen turns and stays black. On MAC OS it turns white. I am able to hold alt and choose the drive, but each still goes black or white. I have tried key commands and all I can do is load Windows in safe mode and nothing more. It will not allow anything more. I stuck the Mac OS disc in and tried loading off of it, but after the apple logo it goes white and stays that way. I have unplugged everything and tried, but no luck. So at the moment I have a $3,000 paper weight. Not sure what could be wrong?
