I charge $99 for a tuneup. I pick up and drop off your PC at your home. Yes, you can do it yourself, but many people would rather someone just do it for them (just like an oil change, for example). I would add to the list: upgrade firmware (not always, but I at least see what is available) and check those somewhat self updating programs are up to date (java, adobe, other programs you have, etc.). Consistently the customer will tell me "it feels like a new PC!" The PC boots up and shuts down faster, has more "snap" when clicking, dragging, launching and using apps. Older PCs work just fine for folks wanting to access the web (e-mail, facebook, etc.) so a tuneup is often more cost effective than the typical desire to buy a new PC (or tablet or phone).
