PC Blowing Fuse Everytime - Help Please

  Sibbo 14:19 14 Mar 2007

A friend of mine says that his parents PC blows a fuse virtually everytime that it is switched on. It's a basic PC with no added peripherals etc. They have a 13 Amp fuse fitted (don't know why), but it still blows. Is it a cable problem, power supply or something else? Any suggestions gratefully received. Thanks.

There is something very wrong if a 13 amp fuse is blowing on a PC power lead. A PC should only need a 3 amp fuse - a 5 amp at tops to allow for any surge and aging. A 13 amp fuse blowing indicates that power in excess of a two bar electric fire is being drawn.

I would suggest that the cable be checked/replaced and if the problem persists the PSU be considered suspect.

For a start a 13 Amp fuse is way too high for a PC, they are asking for trouble by constantly replacing it, they need to have the mains cable and PSU checked by an expert ASAP.

They are the suggestions that I came up with as a start point for my mate, but thought that I would ask here also in case someone could suggest something else. Thanks all.
