[QUOTE="live4soccer7, post: 1617950, member: 337074"] I can not even boot in to Recovery. The computer will get to the apple logo then go completely gray and completely shut/power down. Sometimes the spinning wheel will momentarily come up (not beach ball) and then it will go completely gray and sometimes it will not come up before going gray. Not to mention I have seen the blue screen with lines, the gray screen with lines, and also a black screen with computer still running and the 'kernal panic' screen a couple times. I do not recall the exact scenarios that created each of these. They seem very random and all happen right after the initial chime on start. I have never noticed multiple chimes or flashing lights on the front. I have done the SMC reset and the NVRAM as well. Nothing from those. [/QUOTE]
