Photoshop Freezing during basic tasks

[Lawtz01]

Hello

Lately I seem to be having real problems with Photoshop.  

On the current job I am trying to take simple logos that are black on a white background, and using the selection tool, reverse the black to white and remove the background.  

However, I get so far and photoshop just stops responding.  It is sometimes when selecting and sometimes when trying to save.  Any advice?!

I've looked at task manager when it freezes and below is an example of whats happening resource wise.
Thanks!

PS - I have updated to the latest version and still no resolution.
