The Curse of "Cowboy Keith"...
If you're out in the sticks and need to get a PC fixed, you can usually find some half-baked "expert" preying on the locals, and charging them over-the-odds for shoddy repairs.
"Cowboy Keith" was something special though. I could have made a career out of cleaning up the mayhem he left in his wake, but then I would have had to charge danger money to make some of his "repairs" safe...
One machine had a RAM upgrade, with four completely different sticks of RAM - FPM, SDRAM, EDO and who knows what the hell the fourth stick was, but "compatible" it certainly wasn't. He also claimed to have fitted a "brand new" CD drive in the machine, but I found it was caked with dust.
Another machine got a new no-name PSU which promptly set fire to its own cables (I've never seen PSU cables that thin before or since) and he'd used super glue on a CPU heatsink, to hide the fact that he'd overclocked a slower processor and charged the customer for something faster.
There were several other "experts" I encountered in that job, including the local "computer shop" that complained that I wouldn't send business their way. Maybe if they hadn't stiffed me on a personal order and caused me so much data recovery work with their "generic" (spelled C-R-A-P-P-Y) floppies, I might have been a little more charitable.
Then again, wailing that I was threatening their business and demanding my dismissal hardened my stance somewhat.
