First would like to thank every one for their replies, help and advice! I think I have now updated Windows 10 and drivers that needed doing.
For now the message Activate Windows is not on the screen. The only thing I haven't got is sound. I go to control panel says device working properly. Go to settings says correct driver for device no updated version. So have bought more speakers and will see if they fix the problem.
You have no idea how much this means to me! I have depression and anxiety and rarely leave the house! My computer is my friend, family and link to the outside world! So thank-you all especially MarcTec13 who never gave up!
