Probably best to start at the beginning.
I have a Packard Bell machine. The problems started when my lexmark photo printer hung. Even after restarting the photo menu appeared. As a result I uninstalled, the problem was it didnt unistall completely, I tried a system restore this didnt work and so I tried again, unfortunately now the system restore could complete and I could install or reinstall any programmes. Eventaully I established contact with Packard Bell support (the system is only 11 months old) and they advised a partial recovery which couldnt be completed and then a full recovery back to factory settings. This seems to have worked although I am still not 100% sure that the system is working correctly. The only problem I know about is that when I try to sync my MP3 using windows media 10 I now cannot, I get an eror message that says the device needs to be upgraded, (I didnt get that prior to recovery). Samsung seem to suggest that is a media player player problem and I should uninstall however, I cannot find the programme in my control panel although I am able to play video downloads and music from my library using media player.
Does this help?
