The only way we can shut down the system is to manually turn the power off, which causes the system to go through a scan when we reboot because it was not shut down properly. I ran a virus scan-there was an indication that there was an e-mail error. I followed the instructions (Norton Antivirus 2002) and uninstalled/reinstalled the virus program and ran another scan, etc. No more e-mail errors.
This problem started a week ago when the monitor turned white and we could only reboot the system in safe mode. I took it into the shop and they told me the monitor resolution settings were too high. We did not change any settings?????? When I got back home, the system started up in normal mode, but continuously reboots during shut down. Could there be some settings in the configuration that are wrong?
