Have just fitted a 2nd hand motherboard,it fails to fire up, not a peep but the m/board power on indicator diode is lit green.
I have checked the power unit, the cpu, the memory the cmos battery, the motherboard settings are as per the manual, the cmos has been cleared.
Can anyone think of something Ihave missed or can do before assuming the motherboard is U/S?
thanks in hope!

Did you say you tried a known good PSU?

Also have you tried starting it with only basic bits? no Drives Connected and only one strip Memory no PCI cards only Graphics

Check the wiring to the case front panel VERY carefully.

Though stating the obvious,check your power headers are connected correctly.

Though the PSU's may work are they big enough to carry the load? Also do you know if the CPU is working ok

When testing a second hand M/B I always test it outside of the case - you didnt say if you had done this- with a known working PSU.

many thanks for all suggestions, tried them all and some must be a faulty board
