    Question Help with PSU

    I switched my PC on the other night and after a couple of seconds there was an audible bang and the smell of burning. I opened the case and everything seemed fine inside so I removed the PSU and opened that up and there were obvious signs of burning and damaged circuitry. I replaced the PSU last night and powered the PC up but whilst everything has power - all the fans are working, lights on on the front, etc - nothing works. Both the CD and DVD drive are lifeless, the hard drive does nothing, the monitor isn't working. I've tried connecting everything again and again but with no joy.

    Am I overlooking something really obvious? could the PSU blowing have damaged anything else? ANy help would be really appreciated.

    Thanks

    Have you got another computer or any spare components? You could try swapping the components from your computer one by one into the other computer to see if they're working.

    Unfortunately not, no. We're a one PC house.

    The monitor has power so that's ok, it's just not receiving a signal. I've looked at the GC and can't see any scorching and the fan's working so I asumed teh GC was ok.

    There's a very good chance from what you've said that the PSU has damaged other parts of your PC. It may 'just' be the motherboard however if the optical drives won't even eject it sounds more extensive.

    It's a lengthy process working out what's destroyed and virtually impossible if you've no other setup to swap parts to.

    Yeah when a PSU goes it can take out all of the components its connected to.

    Not good. Try connecting a difffrent component from another machine and see if that works.

    Does sound like some components got fried. Is there any kind of beep code or other form of POST?

    Nope no beeps or anything I'm afraid. The only signs of life are the whirring fans. I had a nasty feeling that it might all be borked. Ah well, that's life, I suppose.

    Thanks for all the replies.

    Sounds like your motherboard is dead as normally you would get diagnostic beep codes from it. What i would do is remove the ram and disconnect the drives so that all you have plugged in is you cpu and graphics card and check to see if your pc posts or gives any beeps. You could even try removing the graphics card if you are still not getting any beeps then most likely its the mb. Another thing worth trying is reseating the cpu as sometimes that can prevent things from booting.

    Out of interest, what make/rating was the PSU?

    @Kalniel - The old one? I've no idea on the make - I don't think it was anything special - but it was rated 300w. I've replaced it with a CoolerMaster 450w.

    @Zeta1 - Thanks for the tip, I'll try that tonight

    My poor old Abit BP6 died is a similar way. No bang but a terrible burning smell ended not only the PSU's life but also my beloved BP6

    If just one component plugged into the PSU has failed with a short circuit (either because of the old PSU failing, or causing the old PSU to fail) then a decent PSU will detect the short and shut down it's output. It is worth unplugging as much as possible.

    Vicar, I believ you are correct. I unplugged everything last night apart from the motherboard and GC and it powers up but no beeps, no signal to the monitor, nothing. I'm taking it somewhere today so they can look at it for me.

    Thanks again for the replies
