Hi all, Don't know if anyone had this problem before, but it's become kinda regular with me that the display would start to flicker heavily at the same time that the computer would freeze completely. Nothing works (keyboard, mouse, etc) and the only way to get out of it is to press and hold the power button and do a hard shut down. I'm attaching a video of what the display does when it freezes. Also, if I try to access the computer via Screen Share from another computer after the freeze, all I get is a black screen. Here is the video: http://files.me.com/daschund/ojol8k Any help? Thanks!
