edit - because this is a horrible massive block of text:

While working at a retail store many many years ago (moonlighted as freelance IT person that everyone came to me for all computer issues) I was surprised to have a customer come up to me asking general computer questions while on the store floor fixing one of the fixtures.

Turns out, she was a regular and knew a few of the store employees, and they told her I was their limited tech person. She describes all the symptoms of a corrupted OS and after 10 minutes of talking, I schedule an appointment on one of my off days to drive over to her place and diagnose the computer. It took me 40 min to get out there, and was very rural (cows, chickens, a small garden, orchard, etc) and found the computer.

Checking it out, after 10 min, I realized it may be better to reformat and start clean. Getting permission, and saving all her data to an external zip disk (told you it was a few 'years' ago) I put my copy of Win 98 back on there for them. Luckily, she had her internet software (dial up, very rural location) and she just had to go through the setup again to reconnect. Installed all her apps and drivers via internet and after 5 hours, was back up and running. Everything tested, no real issues came up (couldn't find one driver, but everything else seemed to work). Grateful, I told her i'll see her at work next time.

On my way out, the family brought me a few things at my car: Bag of oranges, fresh bacon from a slaughter that morning, fresh eggs from the chickens, loaf of homemade bread, homemade jam, and jug of milk from the cow. I went home and prior to my work the next morning, had the breakfast of kings! Not bad for 5 hours of work, plus travel. (enough food for the next 2 days)
