Out of all the info presented along this thread, the power source voltage reports are the most important and yet appropriate measures have not been taken.

First of all, get a good source of light and have a close look at all the big capacitors on the mobo; if any of them is gonflated, you got your culprit. Thing is, there can be more of them. And thing is, they can also go silently dead, meaning aspect is normal but capacity is lost and moreover, they may draw an important amount of flyback current that brings the power source to its knees.

This notwithstanding, the PSU itself may be damaged - bad capacitors inside it - so it cannot supply the required current anymore, hence low voltage under heavy duty. You may visually check the capacitors inside the PSU if you manage to open it without damaging it's internals or cables.

In any of the cases, the (visually) bad capacitors can be replaced by a skilled technician (I've done it a few times, including on my old Jetway SiS630 mobo - 9 caps replaced). Those that do not present any visual sign of damage would be harder to 'sniff'.

If there's no sign of bad capacitors on the mobo, you may try to replace the PSU with a good (tested) one and see if that fixes the issue. But remember there can be bad caps on the mobo that do not present visual signs of damage.

Good luck!
