Hi!
I have an Inspiron 5721 with intel core i7 and the preinstalled windows 8 copy. Since I bought it I´ve had issues with the explorer process, because when I open any foler, it says it's empty, and after 5 or 10 minutes, the folder loads and the files appears, but also maybe they don't appear and the explorer.exe just crash and restart.
The problem appears for a long term of time (days, weeks), suddenly everything is ok and folders and files appear normally, but then the issue come back. I've refreshed the pc like 5 or 6 times, sometimes it works, other times it doesn't, and also I've tried updating the system to windows 8.1 but it hasn't worked. Any idea what could it be?
