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

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

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
