80-90% of all the computer problems that I encounter with machines seem to all have the same fix when it comes to minor errors and issues. The most common fix when troubleshooting your own machine is to reboot. Yes, that does sound like the typical tech support response when tech support doesn’t want to talk to you anymore but that is because it is the most common fix for PC errors. Typically I tell my customers that rebooting weekly in Windows Vista is all that is needed. In Windows XP and earlier I would suggest rebooting at least 2 times a week and sometimes more if the installation is over 2-3 years old.
