When I go to websites or links of websites even Leo’s I get a message on the top of the window saying not responding in brackets, I have deleted all cookies and history files, I have even tried to defragment but even that wont work, that’s says I have to run a chekdsk which I have and I get a message saying remove the F’ Drive which I would assume is my memory stick which is not in the computer , if I have a USB adapter would that cause the fault for defragging.
