Installed Yosemite, Mac since crashed & won't start up
I installed a beta version of OS X Yosemite a month or so back, I'm not sure if this is related, but when I start to work on my MacBook Pro it started to crash a lot and now won't turn on at all.
Sometimes I can access internet recovery, which I have ran several times and all hardware checks out fine. I've got Mavericks ready to boot of a usb drive, but can't seem to launch it in recovery or safe mode.
Anyone have any ideas?
Update
None of these solutions have worked unfortunately. I can still start up in Target Disk mode but when trying to launch to bootable media I just get a blue lined screen.
Does anyone have any more suggestions? I really don't want to have to fork out for a new machine.
Is dit een goede vraag?

I was having a similar issue. My MBP8,2 boots when it wants, I did a fresh install of the official Yosemite and now I'm screwed... Booting up in safe mode, seems to be something with the graphic card.
