>>106137810 (OP)I bricked a Radeon 9600 XT after repasting because I didn't press the fan+heatsink combo down hard enough to get the clips to latch into the board. I turned on the PC, heard a loud CLUNK, looked in the case to see the cooler flopping around next to the GPU. This all happened within 5 seconds, which was enough to completely toast the die on the card.
I also had a close call when I soft-modded my Xbox and my dumb ass didn't backup the EEPROM despite seeing the multiple warnings to do so. Shut off the Xbox after "successfully" installing the mod, rebooted it only to be greeted with an error 5 message. I had to crack the thing open again and learn the hard way how to dump the EEPROM from the board itself. Man, was that a pain in the ass.
