Back up your files to another hard drive, then re-install Windows from scratch after formatting the existing Windows partition.

To avoid all that hassle in future, backup your Windows to an external hard drive as soon as it's up and running again:
Control Panel >> Backup & Restore >> Create system image

I would also suggest you need to get some decent antivirus software installed too, as well as a third-party firewall.
Get yourself protected!

Ty for your response, could you explain how to reinstall windows from scratch? Sorry, I am not really experienced in this. Oh yeah, somehow my computer returned but it says that the repair is failed and my previous windows is restored.
