I ran sfc /scannow twice now and both times at a certain point i get the blue screen of death (computer goes to a blue screen with an error).

Click start then run, type chkdsk /f /r then press enter, type Y to confirm for next boot, press enter then reboot.

Windows will appear to load normally then either the monitor will show progress or the screen will go blank, do not disturb this. This will take an hour or so before it gets to the desktop.

Ok did that but i still have a problem with my firewall should i do sfc /scannow? Firewall problem
