I see there is a few with this problem, where the motherboards just stop working and the only solution to date is replace the motherboard. Surely there is another solution that can fix this. We have over 150 of these and have lost 9 in 1 week. Something wrong there! no capacitors have blown, tried different PSUs still nothing, tried flushing the CMOS still nothing, tried without RAM and unnecessary cables, STILL NOTHING! Stuck now, can anyone help please?

@BenShep -- how old are these 150 computers? Were they all purchased at the same time?
Have you had power-surges (or temporary power-outages, or "brown-outs") in the building that holds these computers, that may have "fried" some of the motherboards?
Are the computers connected to a surge-protector extension cord, or straight into wall-plugs?

We have had them 4 years but was second hand. We haven't had any power surges that we know of. They are on a Circuit breaker, separately fused, surge protected plugs. if we have a power outage then it should blow the plugs before it gets to the PC. We swapped one of the Motherboards out and the next day it died again.

That is not common. Have you tested the building's power-supply for being "over-voltage" ?
On the motherboard, are the capacitors the "old" style (with a "K-shaped" top) or the current style (completely closed) ? If the old style, the top should be 100% flat, not bulging, and there should be no "brown-sugar-granules" leaking out.
