Power Surge?

North-East_Quine

Was fitting new lights yesterday, so switched off the electricity at the mains. I forgot my PC was on. When I went to use my PC it was dead. No life at all. Has it been fried by a power surge when I turned the leccy back on? Is it worth repairing or should I be looking at a replacement? It's about 5 years old and was working fine up untill I switched off the electricity.

If you have no power going to anything, try swapping the PSU first

Try an ESD before replacing anything...

Unplug from the main
Hold the power button in for 10-20 seconds
Plug it back in then try and turn it on

If no life after that...look to replace parts...

what on earth are you on about?

OP v likely to be the PSU, but worth checking the fuses are ok before swapping out the PSU (either in the plug or some older PSUs actually had replacable fuses built in -if it does it will have its own small removable compartment/slot, don't go opening the whole PSU up as that can be dangerous due to stored electrical charges)

New PSUs cost anything from £20-200, the cheaper end being the less reliable / likely to fry your PC on failure however if its 5 years only and on its last legs anyway might be a case to be made for a £20 one (or one 'recycled' from another similarly old machine being junked)

Check the power rating is similar to/above the one you have in now and check it comes with enough/the correct type of connector for everything your current power supply is plugged into on your PC (open the side and check)

Jasx is right, I've had this happen to me on more than one occasion before I found the sense to invest in a power surge protector, before that I'd gone through two PSU's costing me around £130. Oh well, you live and you learn!!
