I'm not an electrician but I some clever heads together

If you have had the supply checked we might rule out spikes and power surges. If you have had the electrical system checked you should not be getting sparks from you socket. If you are then it has not been checked properly. Have you always plugged into the same sparkly socket? It (btw) is arcing the sparking meaning a defective socket. Which I am sure should not have been missed on checking. However I cannot see how that would affect your computer(s) so adversely. It is strange that the various computer suppliers could not give further info on what actually happened to your equipment when repairing or replacing. I presume you have tried other sockets?

Curious how you can see the GPU damaged. The GPU is the Graphic Processor unit used for the display. The CPU is the Central Proccessing unit. But both are normally covered by a massive heatsink assembly. They can't normally be seen without disassembly.
I'm wondering if you are seeing another on board component damaged that's not a GPU or CPU and maybe that part, if correctly identified, would give a clue. Any pictures of damaged parts?

I have seen this problem before. The naturally occurring lines of tectonic EMF are being focused onto your GPU, it only happens very rarely. You need to contact your DNO and ask them to conduct a Incedental Diagnostic Ionospheric Or Tectonic survey.

You mention replacing cables but have all of these machines been connected to the same monitor? Is the monitor connected to the same circuit?

Yes I did see the damage to the graphic card
I heard it sparking and smelled it burning. When I took the card out I could could see the silver solder on the card had gone black. Burnt
I have got a picture
Give me a bit of time to figure out how to upload it from my phone as I have no computer to change the extension of the pics I took
I can assure you it was a burnt graphic card the nvidia 1060 I paid a lot of money for (crys)

Right
I will do that today
I had them monitor the meter before for about a week
They wouldn't do it any longer as they said the equipment is expensive and the only had one of them.
I have heard of EMI
This is the stuff that can make your internet have drops? REIN ? And you can detect it with a medium wave radio?
Or am I barking up the wrong tree?

I did try a different socket in the same room and that particular computer lasted about a week ( forgot which one as I have had so many)
By the way I did think it could be the monitor so I spent a week just using my tv a a monitor and same happened
GPU had to be replaced. To be fair the companies I bought the computers from have been very supportive and even they cannot understand how many times I have components replaced

There is a photo of the GPU after I took it out
You can clearly see the black burnt bits that where previously silver

I'm not an electrician but even I know that a graphic card should not burn after five day's
Those nvidia cards are pretty robust and anyone who has put on in or out of a PCI slot will know

I don't believe damage of that severity would be caused by emi. Do you know any of your neighbours well enough to try your PC in their house and see if anything amiss happens? This may help narrow things down. Also, and apologies if you have tried this, have you tried a laptop on its own with nothing else plugged into it at all except the power supply? Daz

I think SSE are normally booked out for months in advance for doing the Incidental Diagnostic Ionospheric Or Tectonic survey as it seams to be quite a common problem down there.

Thanks to all of you for your time and suggestions
Thant pic was of the previous GPU
I have a pic of the current GPU and something similar has happened and I can see a smal burnt bit on one of the silver soldered places

If not electro magnetic stuff then what the heck can it be?

I don't own a laptop but I have previously and they have had to be returned to the manufacturer with damaged GPU/motherboard
Bearing in mind nvidia normally solder the gpus to their motherboard

I did think to ask my neighbour if I could run a lead across the road to see if still happened in my house
I don't think that would be ideal though as a car might hit the lead . LOL
I can't really go park myself into his house for five days
His wife might not like that ... just sayin

What should I ask the electrician to test for when he comes next week?
I'm gonna ask him to change the sockets and ask him why I see sparks

What else ?

thank you david
I have asked anyway hopefully sse will get back to me soon. By the way I already did the radon report thing online and this is a low radon area.
I don't mind waiting months
This problem Has been blowing up my computers since I move here in November 2013 so waiting another few months won't matter
All I want is to come home from work switched on a computer and use it like everyone else in the U.K. Is able to without fear of it blowing, causing a fire risk or having to ask the manufacturer for yet another refund

I'm just desperate to find the problem

What did you mean by it is common down here? Could it be the mast on the fire station nearby?
