I really don't do anything, but I fix PCs occasionally. I don't own a business or anything, don't advertise, it'* just a word of mouth type of thing. Haven't done any hardware work yet, all I really do is remove viruses and make people'* computers actually do stuff.
Last customer'* PC had 101 viruses, and I kid you not. It didn't even boot up, that'* how bad it was. It'* always funny when stuff like that happens. I think that'* the record, so far.
