Burnt plug prongs on PC?

Replace the wall socket

cut the plug top off and fit a new one also

should resolve the issue

No worries, don't go pulling at the wall socket if you're not feeling confident. Just replace any of the plug-in cables/leads that you can.

Yes, especially those two connected extension leads which will overheat if to long or coiled. Invest in one decent surge protection lead thats the correct length for the job.

Yep, that power lead in the link you posted will replace the one going into the PC.

A blue spark and pop when inserting a plug is often caused by devices with large capacitors (such as PC PSU's) which rapidly charge the capacitors after being unplugged for a period. Some PSU's are much worse than others in this respect. They aren't necessarily a sign that the plug or socket are going faulty. Heat, on the other hand from a plug or socket (providing that there isn't a USB charger in the socket), would be an indication of a fault where either the wires or pins are loose or worn.

I'd move the PC over to it's own wall socket.

Oh and I forgot to mention that the basis of my info above is on the fact that the burning is on the curve of the tip where the prong would initially make or break contact with the female pins within the socket. This would be the location where the current would initially surge through if this was a capacitance related surge - burns further down the pin would be indicative of overloading.

Yes, thanks for pointing that out!

My steps for testing live wire would be...

1) Have a lap/light plugged into the socket and on, then flip the switch to make sure it actually kills the power

2) Phase tester, Test first on a live plug to ensure it's working and you know what you looking for, then test on the dead plug.

3)Remove the socket and test wires again at the back and unscrew wires as needed, without touching them.

4) Test wires again with phase test, just to be sure

5) Before using your hands to work on wires, touch them with the back of your hand, at this stage you should be sure there dead, but no harm in one final test. back of hands is very important, just in case they are live, or the wife/partner has it in for you!!

Thanks, Not a sparky, but though I was tested enough times before starting and my final test, but possibly still doing it wrong, so always open to better advise.

I always do this "final" incorrect test, as sometimes working in tight spaces, sockets, overhead, light fixtures etc. accidental touches can happen, and not having the most up-to-date tools probably doesn't help either to striping, adding multiple wire (loops) to one contact etc. (Also I probably should have said brush rather than touch but the same issues as you highlighted)

So I will keep in mind in future, to skip my last test and try to always work without touching the exposed wires at all.

Rather than using the back of my hand to pinpoint live circuitry, I prefer to simply lick the wires with my tongue to quickly identify which, if any cables are carrying a live electrical current.
