Hello and welcome Smithy sorry it seems you have had quite a number of views so I shall start the ball rolling and say that in the dump files there are references to a graphics driver fault ( I am no real expert but these are there) so have you updated the driver for the GeForce GTX 560? if not this is it Drivers | GeForce and if you have and the problems started there then you may have uninstall it and revert back to a previous version. Let us know how you go.
