I am trying to reformat my laptop but it keep rebooting. Computer starts loads for a while and on the windows install screen it reboots.

My parent was trying to log in to yahoo, and I don't know where they got the number for yahoo customer service (because as far as i know they don't have any) but apparently they allowed access him to our laptop and was asking for money. So now i am reformatting it but its not working.

any suggestions on what I could do?
