dead gigabyte motherboard???

[lancsDavid]

I've just built a system using a gigabyte GA-K8NSC-939 motherboard & an AMD X2 3000+ chip (socket 939)

when i turn it on, there are no lights or LED's on the motherboard & the CPU & chassis fans just spin periodically

ie:- they both spin for a second, then cut out, spin for a second, then cut out (& so on)

i've swapped PSU's three times. 2 of the times using a 700W thermaltake that powers a much bigger Athlon X2 6000+ system & a brand new OCZ 600W stealthstream

(both of which produce the same stop-start- dead-motherboard behaviour)

i've swapped the RAM, for another stick of DDR that works in another system

i've done the jumpers on the CMOS

so all i can think is, it's either the CPU or the motherboard

not knowing whether the GA-K8NSC-939 motherboard is supposed to illuminate in some way to indicate its getting power from the PSU, i can't pinpoint the dud component

any help much appreciated

Could be corrupt bios. What was the last thing you did before this problem cropped up?

Try disconnect every drive & expansion card.
