double check that all power cables are fully plugged in on the motherboard
CPU cable, main power 24 cable, 2 cables into the HDD caviar black, 2 cables to the optical drive, all cables of the case.
Did you use the standoffs under the motherboard (or raised bumps if the mobo tray has those) ?
Also, reset the BIOS to defaults by using the jumper and/or removing the battery (with the PSU unplugged or switched off so it isn't supplying +5VSB).
The Mobo iz well fitted with gold bumps, yes.
What should the jumper setting be? I left it as it came.
