| 125633 | 2003-03-05 01:38:00 | After turning on computer, heard big pop and smoke coming from case. I removed power supply which had bits rolling around inside it (fuse). Is there a way of testing motherboard and peripherals without risking another power supply? BTW the main plastic power connector on the motherboard had slightly melted edges. No damage to any other peripherals. Does this mean the MB is most probably fried? Thanks |

| 125635 | 2003-03-05 02:30:00 | Who says computers are boring? :D It would be unusual for any fault on the regulated side of the power supply to blow a fuse . Least of all explode the fuse . The normal cause of such a violent event is one of the high voltage parts becoming a short circuit . That is usually the diode bridge which rectifies the mains, or the capacitor which stores the rectified 320V DC . The mains input can provide lots of current to a short circuit . (About 6500 A, I think) . An overloaded supply will normally just shut down, which is a much less exciting thing . So the rest of the computer might still be OK . Is that connector melted or does it just have rounded corners which you have noticed because you are thinking "@#$%^&*" and "$$$$$?????" in your shocked mode? |
