Wise man this is a work provided lap top R and B So I got no say.Nothing but trouble since day one both hard ware and soft ware.
Loath to add any programs to it due to problems in the past, it is staying stock standard.
Have tried all your suggestion to no avail.
I only use the lap top occasionally to visit Demonland, mostly use my Desk top ( windows 7 ) and iPad
No big deal really I have the above alternatives
