Check your RAM, it might be the fault. Run virus and malware scans. Use boot scan if available. If everything fails, reinstall OS, since you have back up of your work. Only you know your browser history and can tell if there is possibility of infection. If an infection is not the case and the re-installing does not work, then it is most possibly a hardware fault.
