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

If I put my computer on the floor rather than on the computer shelf will it be grounded?

Ha, ha very droll! To understand ground circulating currents you have to understand the relationship between capacitance, inductance, voltage and currents in a computer system. Circulating currents can cause problems when output currents cause a difference between the actual output voltage and the feedback voltage as well as when the output ground currents move the power supply's analog ground off its true ground. They also cause problems when the output current in the supply and ground rails interfere with the delivery of an accurate voltage to the system and when the circulating currents are in loops which then radiate excessive electromagnetic interference into the system causing it to fail. Thinking about it, the only way to destroy this many computers with ground circulating currents, is by corrupting their bios chipsets. Are you sure you are not loading some computer virus onto your systems?

Computer viruses do not destroy electrolytic capacitors! Daz

You never seen The Matrix; red pill or blue pill?

My eyes are bleeding
Wtf does all that mean? :mkungfu:
Whoozzzze something flew over my head

 

[beachlover]

Well I have to agree with Daz
I don't have a computer virus because quite simply .... I don't have a damn computer

 

[beachlover]

Mama always told me not to take pills from strangers
Just sayin

I think I'm out of this one now. Been quite entertaining though! Thanks Daz

Look I'm sure you already realise and are just playing along, but to save you embarrassment just in case - don't ask about the final thing on your list, just look at what the first letters of the words spell !

Well there is one breaker marked Solar PV that could be a clue...
But my gut feel is an issue via the HDMI or DVI cable. What's the monitor connected to the computer.

Benq monitor bought new in 2015.
It was happening before on my old Asus monitor
I had a new motherboard GPU ram and PSU replaced in November this year. I decided to rule out the monitor by using the computer via my TV with brand new HDMI cables to rule out the old cable.
I also bought new mouse and keyboard to rule out any fault on the USB
I made sure I used nothing else.
Within a week it happened again and the GPU failed

The GPU isn't the most sensitive device in the computer. CPU RAM and more are on the motherboard before a plug in card.
To blow things on a plug in GPU card or GPU motherboard I'd be looking at what connects via the monitor.
But again as I said before a UPS tgat connects to the mains and then to monitor and computer are a must.

The electrician has been
I asked him the questions you helped me compile
1) he said Wyler McNeil in Easton cu is ok and is now passable by the power law peeps who govern electrician

2) he has turned of the solar panels and disconnected from the board

3) he looked puzzled when I said about quality analysis monitoring but he said that is what SSE have done

4&5) he said that was collage lectures stuff and has little use practically - his words not mine

7) I forgot what he said about TN-S or TN-C but he did say the house has had a rewire in 2008 or later because he says the wires have the new colours

8) he PAT tested the freezer and said it passed. However he said we should have used shielded cable to run it from the house to the shed.

9) he asked if the person who recommended an IDIOT Tests was for real ..... bbbwwwwhhhhaaaaaa

He voltage tested the board and sockets and said they were stable at 230 v and this was lower because of a v-phase something or other and a voltage optimiser.

He also put on a brand new surge protest socket on the one where I saw sparks coming from

Nothing more to be done regard the electrics I guess?
Just have to wait and see if the next computer lives or dies.

I'm thanking you all most dearly for all your help advice and brain power.

Wishing you all happy holidays
