Press power switch... power light comes on, CPU fan runs, keyboard lights flash once, but no signal on monitor, no HDD activity, and no beeps.
The monitor light is flashing suggesting that there's no output at all from either the onboard ATi 9100 IGP or when I used an AGP4x Radeon 7000 card, although the graphics card is getting power through the AGP port because the fan is running.
I've checked the processor seating (and then reapplied thermal paste before replacing heatsink/fan), switched the RAM to a different socket (there are 2, one green one purple), and checked all fan/power connections and jumpers.
I figure either a dead mobo (brand new) or CPU (brand new), but was wondering about any other suggestions before I reinstall the old system and send the new one back.
Only thing I haven't tested for yet is the mobo shorting with the case.
Any more suggestions?
I couldn't find any 4-pin header on the board for the case speaker, so I assume that the black circular component with "BZ1" is a buzzer for the BIOS beeps.
Thanks in advance
