There's no such thing as a silly question here. A lot of what we do is small stuff that's been annoying someone for months - a printer that stopped working, a laptop that takes ten minutes to start, an email account that won't behave.
Because we work at your place, we can see the actual setup: your desk, your WiFi, your printer, the way you use it. That usually makes the problem much quicker to find than describing it over the phone.
