Lenovo issues with windows 10
I have a windows general problem since i've upgraded to windows 10 with my lenovo laptop
At some points, the windows bar does not respond anymore, be it when clicking on the "window" or on the logos on the right side. Plus, there is no sound anymore or sometimes you can't even play a music or video, like on youtube you click on play, nothing happens. Or even on a music software on my computer (Itunes for example).
It looks like lenovo hasn't done a proper job to be prepared for windows 10 or maybe I have a software or something that conflicts with windows 10. I have no idea really but could you please advise me what this problem might be?
Thank you very much
