a while ago i had a Mega STE that worked fine until one day i switched it on and the fan on the PSU ran very fast! (like it was getting too much voltage) so quickly i switched it off but was clearly too late
anyway on removing the PSU to test it i found the 12v rail was outputing 22v!! didn't get a chance to test the 5v as it blew up in front of me!
anyway needless to say the Mega STE is dead, however i have found the scsi board to be ok and working still and so is the memory
so not wanting to scrap it my question is what would be the first 5v component to get hit by high voltage?
