MBP 2010 constantly fails to get past half way on startup bar, then crashes
Hello everyone :)
My MBP 2010 has recently developed a problem, whereby when you switch it on, it constantly does not get past roughly the half way point on the startup bar under the Apple logo, followed by then what looks like a load of 'Terminal' type code, that lists it's way down the startup screen & then the computer crashes/goes to black screen, or shuts down...
I've tried all manner of starting it in Safe mode, Recovery mode etc, nothing seems to work... Luckily I have my entire HD backed up to date, but it's of no real use to me, unless I can actually get the laptop to boot up properly in the first place!! Is this hardware/component failure of the mother board, or something wrong with the HD?
Thanks in advance!
