What is your operating system?
Do you have the installation disc?
Do you want to format and reinstall windows?
Ok so what you want to do, we have two options:
Reformat the computer(easy) or try to fix the issue(difficult)?
I have not recieved the information about the operating system and also not having the disc.Can you tell what is the operating system?
You don't need to contact me again, I will give you the process of reformatting harddrive and installing the operating system, you just print the info or save the info so that you can use when you get the disc.
In case you need to contact me again, you can bookmark this page using Ctrl + D and later you can click on favourites and the bookmarked page to reach here.
