I don't know, I would not feel right charging my family or friends for tech support. If I don't want to do it, I will tell them to call the vendor, or I'll look up a computer shop in the town they live in and tell them to call the shop. If I'm too busy, I say that I'm too busy to help them out right now, but you could call X and they could help you. If I just don't want to help them, tell them that it would be easier for them to get the computer fixed by someone local. If they want, I tell them that I will fix it when I have time if they drop the PC off at my house. That eliminates me driving to their place to fix their PC.

If you aren't too busy and don't have much else planned then why not fix their stuff? What goes around comes around. I've always helped my parents out with buying computers and fixing software problems even though I'm 1500 miles away. This year I helped my dad buy a new Palm model, and as a thank you for that and all the years I've helped them with their PC problems he bought me a Tungsten C. Granted, that does not come close to an hourly rate that I would have charged if it would have been a business, but that token of appreciation was indeed appreciated.
