Did not install any new software oir hardware but simply closed computer and had issues the next day upon starting. WOULD NOT RESTORE to ANY previous date saying unable to restore original directory or something similar. Did registry clean, cc cleaner, spyware and virus check with Avast vand Super Anti Spyware.
