How can we speed up our computer?
The HP s5390a desktop computer takes a long time to boot, change users, open programs (apps), save and view the tree and rename folders and files.
We have ADSL wi-fi, and run Norton 360 as security.
4gb ram 3.87 usable
64 bit operating system x64-based processor
Intel Core i5 CPU 650 @ 3.2GHz
We bought it with Windows 7, upgraded pro then V8, then 10 pro. It is 6-7 years old
Should I back up and reformat the drive. Then what should I do to restore files and programs without messing it up again.
