HI, My friend's PC was working ok but when he next turned it on, it was as dead as a door nail. No movements at all. I thought it could be the fuse of the 3 pin plug and replaced it with a new correct 5amp.Process of elimination as a first step. On plugging it in, there was a bang from near the PSU. I thing the PSU was probably dead before I replaced the fuse. Any ideas before I go and invest in a new PSU for her.Would appreciate quick replies as it a hol. today and I have some time. THanks.
If there had been a power surge, such as during a thunderstorm, or electrical supply glitch the fuse could have blown and the psu could have been damaged. Replacing the fuse would perhaps have given the psu the chance to blow altogether
It's not possible to say exactly what happened or what has been damaged without examining the computer
However, since the fuse blew and the bang is said to been "near the psu" I think a fair first step is to try a new psu, especially since they are not too expensive
I don't think I would worry about further damage at this stage
