If you haven't made recent software / hardware changes, it is possible that doing a system restore to a date prior to when your error started happening may fix it.
It is also possible your computer has become infected with virus / malware, so do some scans with your Anti Virus APP. Also, give Malwarebytes Antimalware a go. They have a Free Scanner which you can try that is quite effective.
