Hey guys been having problems with my laptop during the weekend with it hitting sudden 'lag spikes' usually during and after which I can't do anything at all on my MBP. But this evening I restarted it and it's refused to turn back on. When I boot it on I get the blue screen with the Apple logo and the loading screen then some error messages show up (http://i.imgur.com/i1yxTRjh.jpg) and it reboots itself. The next screen it shows is the blue screen but with 'Your computer restarted because of a problem. Press any key or wait a few seconds..." Any help at all will be much appreciated, I've got some coursework to do for the night and this is my worst nightmare!
