Thanks for that dude but what will it do?.....also I'm not very good with technical stuff so do you mean I have to run it from c prompt?.....A bit of tech help might help me if that's possible..buts thanks so far
It'll check the integrity of your windows files and fix them if it finds anything wrong, assuming you are running windows 10, click start, type cmd, right click the command prompt option that appears and click on run as administrator, type sfc /scannow into the new window that opens and hit return, it'll take about 5 - 10 minutes to process generally and will let you know if it finds anything.
