When given the choice between calling up the IT department or repeatedly restarting my computer until it magically begins working correctly again, I usually choose the latter. And here's why:
[$15.95, X-treme geek]
If you call up the tech guys, you're basically at the whim of embittered computer prodigies who are actually referring to these die whenever you ask them a question.*
Actually, if hitting restart isn't working for you, you may just want to pick up a pair of these yourself.
*Disclaimer: All of the IT people I've ever known have been extremely lovely people, only existing to make life easier for the likes of me. All computer problems are due to the idiocy of their users. Especially that time I spilled hot tea with honey all over my keyboard.
