Boots only sometimes, black screen-video issue?
I have a MacBook Pro 15", A1226. Last three digits of serial number are X91. Here's the issue: when I turn the system on, sometimes I only get the fans to spin and nothing else. Other times, it will chime, and the hard drive will click a bunch, like it's booting normally. I don't get any image on the screen (not even a dim one), or an external monitor. The front white light stays solid and isn't dim. I've tried switching al the ram around and using on ly one stick, no difference. Is this a video issue, and could it be a cause of why the computer won't always boot?
