Macbook Pro(2011)

I have a Macbook Pro from 2011 which was running very slow, and had limited space available. so I have attempted to reset it back to factory settings and I have loaded OS X Mountain Lion, and I have managed to add subsequent updates fro this operating system.

However, I cannot seem to upgrade the OS with the Mavericks version. The App store does not show any further updates, and I have the 'Install OS X Mavericks', in Finder but when I try to load the new version, all that happens is that my MacBook essentially restarts with message of a problem which I can send to Apple, but no install icon or message appears, so I cannot move my MacBook forward.

Can anyone advise me one this problem, and what I can do to fix it?
