I tried to solved this by checking on forums but so far nothing worked. Since few weeks now my computer started to have issues on startup, when going on 'control panel/ System and security / Security and Maintenance / Reliability Monitor' I can see that almost everyday 'Windows Explorer' or 'C:\Windows\explorer.exe' has this issue 'Stopped responding and was closed' with desription 'A problem caused this program to stop interacting with Windows.'
