It's really looking like a PSu problem but I would like to check something else.

Download WhoCrashed from the link in my signature below
This program checks for any drivers which may have been causing your computer to crash....

Click on the file you just downloaded and run it.
Put a tick in Accept then click on Next
Put a tick in the Don't create a start menu folder then click Next
Put a tick in Create a Desktop Icon then click on Install and make sure there is a tick in Launch Whocrashed before clicking Finish
Click Analyze
It will want to download the Debugger and install it Say Yes
WhoCrashed will create report but you have to scroll down to see it
Copy and paste it into your next reply

Crash dumps are enabled and no crash dumps have been found on your computer. In case your computer does experience sudden reboots it is likely these are caused by malfunctioning hardware or power failure. Then it's suggested you contact the support department of the manufacturer of your system or test your system with a memory test utility for further investigation.

This means the problems are not caused by a driver.
I didn't think it was but wanted confirmation.
We have checked
memory
hd
chkdsk hd
SFC
drivers

The only issues left at this point is either the MOBO or the PSU.

You have tried it in a different outlet
With and without a surge protector.
That takes out the possibility of electrical brown outs or spikes.

That is alittle harder to do because it takes a trained eye to see burn marks and such.
The one thing you can check is to see if maybe a Capacitor is leaking or bulging.
Capacitors look like mini tootsie rolls standing on their ends. I am including two pictures. The bottom picture you see the little blue things that stick up... those are the capacitors. Yours may be blue, black or grey.

On inspecting the motherboard I did not see anything out of the ordinary. I did however notice that the power supply is running pretty hot and also wondering if it is in the wrong way around. I pulled it out to see.


What do you think?

could it be some mechanism for shutting down the system malfunctioning and giving a false positive?

I notice the psu fan is facing a wall of metal instead of a good air supply. That may be causing some issues for you.

ok i inserted the psu the right way now! can u believe that?, professionals putting the psc the wrong way around!!..the fan is facing down now. Oh boy what a difference on the ventilation! :)

Hmmm I suspect this may have been the cause all along?...heat building up in the psu and
shut off mechanism?

ok hopefully this solves the problem!

the testing continues!....
