so, on my lunch break my dad called me and said that his office computer was turning off, then it started to smoke. i spent my lunch break swapping his system over to his other computer. he's a dentist and has a software suite with patterson eaglesoft. basically his office will grind to a halt without any computers working. he can still work obviously, but will not be able to submit any electronic claims or do any billing etc. currently he is working on his second computer, he just cannot send any electronic claims because his second computer lacks a modem (he uses dialup because broadband is not an option in his building) when i got home i took a look at the computer. the power supply stunk like burnt electronics. i had a backup computer at home that was prepping to bring into his office the following day. i got the backup computer all set to go. i wanted to check the hard drive of the busted computer, so i put it in as a slave. bad idea. the computer would not turn on now. i removed the slave hard drive and the computer would still not turn on. that hard drive ended up frying the entire backup computer, mobo, power supply - even a hard drive caddy tray holy fuck!! apparently one hard drive killed 2 computers. good thing they are older amd computers. i'd be fucking pissed if i would have killed my c2d rig that i just built. i managed to load his latest backup image from a dvd onto my c2d machine. now i'm running into the problem that i do not have a working modem - both are dead. i think i might have to process his e-claims at home while i wait for a modem to arrive. i would have never thought a single hard drive could cause so much damage. initially i thought it was just a dead power supply. CLIFFS: dad's dental business computer dies. thought it was the power supply, turns out it was the hard drive. i figured this out after it killed 1 additional computer.
