Hi,

I could do with some help with how to proceed next.

I came home and flipped the switch on the wall socket which my computer is connected to through an extension lead with surge protection. Sometimes the switch makes at the wall socket will make sparking sound when switched on and this time it was noticeably louder.

My computer failed to power on but all devices attached to extension still had power. I replaced the fuse on the PSU cable and tried again. This time a pop was heard in my computer but I'm not sure where. I tried a differeent PSU cable as I had run out of fuses and this time upon plugging the cable in to the PSU it triggered the fuse for all sockets in the property to trip.

There's no burning smell or signs of burnt components (yet). I don't have any spare components at the moment so I feel my options are limited right now, so my next step is probably buy a new PSU. Not sure what to try next if that doesn't work.

What are the chances of other components being knackered if the PSU did blow? It's a fairly good quality one: Corsair HX620.

Appreciate any advice you can offer to help deal with this.

Just my luck to have this happen as I was about to splash out on a new GFX card!

Thanks

Your psu SHOULD have protected the rest of your system. Its supposed to sacrifice itself and protect everything else, after all its why we buy name brand psus and not 1000000watt christmass cracker jobbies for £5.

Id say buy/borrow a new psu and replace the extension socket.

Does it do that if you use another extension/device? It could be faulty wiring in the socket causing that. I don't know if that could cause the PC problems though but it is something that should be checked since it shouldn't be doing that and could potentially be dangerous if the main circuit breaker fails to do its stuff.
 
Thanks for your replies, I'll have the sockets in the room checked out as a few of them do it.

I've bought a new PSU so I hope that's all I need to replace. I had a look at the PSU and can see a component has burnt/popped. Couldn't get a good look at it as I didnt open it up but it has copper wires wound inside and a rubber/plastic sleeve over it with an open top.
 
If nothing happens with a new PSU in there, try wiring your reset button up as a power button - power buttons can be surprisingly fragile and may die with the PSU, caused me a bit of stress when my old Corsair went bang!
