Windows stop sharing videofiles

Hello .

I having a huge problem with windows stop sharing files in my home network . All the maps are there like I left them . But the devises say it empty when it's lot of files to share . Only solution today is a reinstall . Please somebody .

I have reinstall c drive 10 times this week already

Computer :
Msi h87g43m 1150 socket
Processor i5 4690k
Hard-drive . Samsung ssd as boot divise . 2 3 tb wd red as the backup and file share system .

Networking : is a dlink 615 with the build in network from the motherboard .

A clue is the sharing network needs to be reactivated every start up. Is that normal ?

Some parts have I time of over 4 years I think . So it have some years on it now .

Where I begin here ? Can it need a new bios battery ? . Correct me if I wrong but it some how helps the computer to store some settings

 

edit..it seams to just share the stuff on c ..not on the other drivs

May be solvd

Same thing happens aigan
