i can suggest a solution this will run the explorer.exe automatically when your OS boot
1. Download glary utility from
http://www.glaryutilities.com/ . Its a freeware
do a 1 click maintenance then reboot
if the problem still continues then2. in glary utilities go Module>optimize and Improve>Startup Manager
3. In startup manager add program name whatever you want to name in path type explorer.exe and dont toch the third one and then click on ok
reebot and now the problem shoud not arise
