Thanks for your reply. What do you mean by 're-installing everything'? I bought the computer second hand about a year ago so don't have any instructions/discs etc
what i mean by re-installing everything is:
remove EVERYTHING and then do a clean install of your operating system, and to do this follow my "guide"
😀
if you have windows 7 or under then visit this:
http://www.techverse.net/download-windows-7-iso-x86-x64-microsofts-official-servers/#
don't worry i have downloaded stuff from there before so...
😀
if you have windows 8 or above then visit this:
http://getintopc.com/softwares/operating-systems/windows-8-1-download-iso-32-64-bit-free-official/
i know... this website seem a bit virus like, but don't worry it isn't
😀
when you have downloaded the correct file it should be/is an iso file.
then you need to get a USB drive with at least 8gb of space.
put the usb drive into your computer and then download this

this is a program that makes a windows installation program
run the program and choose the right file

hope this helps.
