Yeah I used to do the same a few years back. Had a good customer base, mostly elderly toward the end.
But got sick of getting 30 calls a day and trying to explain to them where the power button was.
Then there was the gaming pc builds for say a customers teenage son. You'd get a call saying the pc wont turn on anymore and you'd find three inches of dust in the thing, so it was overheating. Or it was plagued with viruses because of the porn sites they'd been in. Funniest is asking them about those sites and they deny the lot.
