Shortly after I deleted temp files, I began receiving a series of system errors 1816(null), a proposed change in autoexec.bat, configsys, hosts, "can't enumerate devices and eventual system freeze.

Profess starts with notice of failure of internet connection, then a question regarding proposed change to autoexec.bat, then on to other notices.

I reboot and all is well. This happens approximately every twelve hours.

Suggestions?
