Before you consider an issue a real small business computer support problem and call your small business
computer consultant, always reboot first.
Exit out of whatever files and programs you're working on and do a Shutdown and Restart sequence to reboot
your PC.
If you suspect the problem involves something hardware-related, such as a network card, modem, mouse,
keyboard, or sound card, go one step further. Shutdown your PC. Turn the power off for a minute or so and then
power your PC back up again.
