2) When I set the memory and restarted my PC it reverted it back to "System Managed Size"
3) I uninstalled the keyboard drivers and software and I am now using a spare Logitech keyboard, I was able to boot fine and even play a game for around 5 minutes, after closing the game windows froze and I had to restart.
*Edit* I'm currently uninstalling Visual Studio 2012, Bonjour (Apple) and uTorrent as these are known to cause problems.
After uninstalling these and restarting my PC, I got a BSOD that said "DRIVER_IRQL_NOT_LESS_OR_EQUAL"
