I was just wondering how to reset my DELL computer, the reason is that every time iam on the internet my explorer always closes and sometimes it just freezes for some reason.And not too long ago there was too much things on my computer so i deleted lots of things and i think some of them were for the computer and i think thats why iam having this problem is there a way i can fix this problem or just reseting my computer to like the day i got it?
