Taking apart a computer and knocking out the yellow lead from the spare floppy power lead socket . Then thinking it would be fine and only a few volts I powered up the machine after inserting a brand new 64mb sd ram (when it was not so cheap). think all was well then standing the case back up to pop the case cover on.
Well the lead flopped onto the ram stick and set it alight. poo
I then tried to exchange the ram but they made me buy another one
