From that testing showing no 5V rail then I would assume that it could be the Power Supply. PC shop should be able to swap one over for less than a hundred or you could get one & swap it over yourself. Just need to swap cable for cable. A reasonable quality PS is about $70-$100 for a 430 watt.
Newer model PS's have sata connectors whereas older style had molex to sata converters for your hard drives. They all have the same connectors, some just have more.
There will be two connectors to your motherboard (one large one and a smaller one that will have a connector somewhere near your processor), one each to your HDD's & DVD and possibly others to the case fans.

We have to start thinking about what sort of a world we are going to leave for Keith Richards after we are all gone.

Unfortunately, the 5V rail may be shut down by a failure on a daughter board or disk drive etc. Not as common as the Power Supply rolling over.

Given it happened when a USB stick was inserted, pretty good chance the 5V rail is dead.

I try not to jump to conclusions. Still do, but rarely with technical stuff.

I'm with you. Some of the cheaper USB sticks have a bad regulation issue and draw to much. I've seen 3 this year at work.

It was a cheap USB which I have been using for 3 years.

Had another go yesterday with the multimeter and a paperclip.
Measured the 4-pin to the hard drive again and the 20-pin to the mobo.
All voltages are as they should be, only the 12V is a bit low: 11.6V
The other are all there: 3.3V, 5V and 0V.

Are you saying you now have 5V at the hard disk on the red wires?

Yep, I couldn't measure it correctly last time.

Lost, I am not willing to spent another $1000 within 2 years on a computer.
I am using the laptop although it is slow.

Luckily I tested the harddrive in another computer.
All data is still there.
I have it copied to my external harddrive.
It is now less a problem, more an inconvenience.

However  still would like to have it done.
When we are back from holiday I look further into it.

Finally, I dropped off the computer at a repair shop.
But I am not happy.
The motherboard was gone so they replaced it.
When starting up and running fr awhile it was shutting down again; CPU gone as well.
The repairshop reckons it has been a power surge.
So they are replacing the CPU as well, with a better one.
Sweet.

Now the not happy part.
They will replace the X2 260 chip what came out of it with a X2 270 chip.
Hang on, I bought the computer with a X4 640 chip.

So:
1. they messed up with the chip they took out of my computer
2. the guy who sold and built me the computer ripped me off.

Somethign to be said for building your own..

X2

Plus, make sure the warranty is long enough to cover how long you want to keep it for. If a Dell mobo dies then it is costly to replace out of warranty as they are usually not an off the shelf PC shop replacement.

No one suggested the memory??? Maybe it sh*t itself.... maybe pull the sticks out & run them vigorously over an eraser to clean them?? Check them for damage.

That was my first thought as well, memory.

Taking it to a PC repair shop is risky, if you know nothing about them, some can and will tell you anything to increase the dollar count.
It may very well turn out to be a bad memory stick, but they tell you they have to replace this and that, but only really replace the ram.
