Ok, I've worked out it was the something in the Cache folder of my Chrome user profile folder causing this issue. If anyone encounters the same problem this may be your answer.
I worked out the problem lies somewhere in my Chrome user profile folder. Created a new profile folder and the issues are gone. Somehow I need to work out what exactly is causing the problem so I can retain my original profiles with all of my settings, bookmarks, history etc.
