Hi Guys Specs are a 2009 MP, 2.93 Quad, 12GB RAM. I'm looking to move from my old spinning drive to put my boot on an 256 SSD I have spare. I've got Yosemite on a USB stick and start the installation process, choose my drive and away it goes. It restarts as planned after about 10 minutes but that's it. Computer restarts and the monitor just stays black with an orange indicator light (no input). It is prudent to mention I have a flash PC GTX 680 in there. I stay at a black screen for quite a while when starting the computer, with the same orange indicator light; however after about 60 seconds the grey boot screen comes up no problem. No I get no further than the black screen. Any ideas? Should I remove the old hard drive with my current boot on it? Any tips on how to get further would be greatly appreciated.
