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

[beachlover]

Hi everyone
I have the strangest problem that no matter who I ask in the trade they seem to scratch their head and tell me to buy a surge protection unit. I have bought a million surge protections units Just sayin

Here is the problem and some of things done over the past three years to try to resolve it ....

I seem to be getting some sort of problem that is blowing up my computers. No amount of electrical test seem to find the faults. It's not just bad components or the company's where I buy the machines either.
I have estimated Over 16 devices blown and 47 repairs since 2014. This is from five different companies where I have purchased computers with a warranty.
Computers last typically for anything up to two days or two weeks before failing. This most common failure benign burnt chips on the GPU s

It is my understanding The modern motherboards have built in surge protection and they go into protection mode when a surge is detected. I have had this happen but when I next switch on the computer the GPU is damaged or becomes damaged.

Work carried out on my electricity by the electrician working for the housing association house I live in

1 - four different surge protectors bought
2- ups bought with surge protection
3 - 2013 a full electrical test on RCD panel and all sockets - passed
4- 2015 another full electrical test - passed
5- electric supplier monitored for surges from outside- none detected
6- two sockets faceplates replaced (the ones used for my computer)
7 - independent electrician hired tested sockets. No fault found.
8 - Eco Max Home Voltage optimiser fitted on RCD panel and set to 230v

Other information.
No other devices in the house fail and we have two HD TVs, a MacBook, two iPhones, router, and the usual lamps, kitchen equipment. New mouse,keyboard,HDMI cables,USB cables purchased

UK based electrical system with RCD panel with an additional Volt regulator fitted. We have 240 volts coming into the house
The housing association also fitted a gadget that regulates the volatage 230

On the last occasion I saw the the computer component frizzle smoke and could see the damage. I'm really worried about a fire risk
I have on occasion see sparks come from the switch on the outlet.

I would appreciate your thoughts on why this is happening to me as three independent electrical test and Electricians tell me they can not find or think of what could be causing it.

No computing for me for a while

Many thanks

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

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

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
