Hi, I recently acquired a MacBook Pro A1260. I know this model is old, but I have no idea why it refuses to boot fully. When I try to boot into OS X, it freezes halfway through or restarts halfway through. When I try to boot into windows, nothing shows up but a black screen. Has anyone encountered a similar problem on your Mac? PS: I know that this model has a very common video issue, but the Apple logo screen does not have artefacts which makes me believe it was because of some other reason.
