Ok my first post so first a hello, now I have two motherboards both the same model and both with the same faults, they power up for 5 sec then the power supply turns off, tried with all cards detached (same) tried with all ram removed (No Beeps) tried with new chip (Same) so come to conclusion they both faulty, Have read on the net that these were supsetable to a fault due to the front usb ports, yet these have never been used, contacted the help desk who asked for serial numbers, both have white stickers but numbers do no represent serail numbers and there are no others on either boards, the number from one states 401125 01230 and has a bar code above it, I have had these for two years now but the store that sold them has gone, any help plaese..
