My son Timmy didnt like his moms new live-in boyfriend Wayne. This was back in the days when people ran BBS's. At that time i didnt even have a computer. Anyway, from what i was told it took untold amounts of hours to build a BBS. And i believe he had other, similar items on his computer in which he had a lot of time, maybe a second BBS, not sure on that part. My son got mad because Wayne ate the last of the ice cream so he formatted Wayne's hard drive. Wayne called me so i told him to spank Timmy on the rear only, and when he wasnt so mad, lol. Seems to me Wayne told me it would be 30 or 40 hours for him to rebuild what he had on the computer!
Now that i know computers, i have customers. I had one bring in his pc, it wouldnt start up. He left it and i walked by it and called the customer back in as he was leaving. I told him i bet he just drywalled a lot of his house. He said he had a raised ranch and he drywalled the lower level. He wondered how i knew that. I told him that normal dust is grey but the dust on his pc fan was white! Later i took the case off and the rather large P3 heatsink on the cpu was totally full of drywall dust, same with the fan of course, and vast amounts of drywall dust everywhere. I had to take apart the whole pc and the power supply. A total mess. Once back together the pc ran fine.
