PC blowing fuses

    Ive been having problems with my PC for past few weeks. It appears that the PC power lead fuse keeps blowing. A few times now when its bein in stand by position and I go to turn it back on, the PC just dies. When i change the fuse in the plug it works again. it plug says 5A so I have been replacing it ith 5A, i even tried 3A and still same problem

    the PC used to be left on alot but since this has been happening I started to power it down as I thought this was maybe why it was acting this way and becoming overheated.

    A few times also the display just freezes and the only thing I can do is pull the plug but when i go to restart again..nothing!
    I also swopped the power lead with the monitor once just to prove it was in fact the fuse on the lead and not the PC

    Someone suggested to me that maybe it was a problem with the fan in the tower abnd this was overheating and causing the fuse to blow but I have no idea how to check if this is so.

    Anyone got any recommendations?

    To me that sounds like a power supply problem.

    If you are blowing fuses thats because you are drawing more power than you should be.

    SOmething might be shorting out in the case. For the PSU to blow a 5amp fuse it'd have to be drawing just over 1000 Watts I think the PSU would die before that happened.

    simple things first...

    change the power lead

    try another outlet


    could well be a short also as lump said. a stray screw inside the case??? god knows!
