I've seen similar topics on this forum and others but I'm hoping that by posting it here and working through the problem methodically I will stop freaking and spazzing.
When the motherboard is sitting outside the case the system boots without error. When the motherboard is installed there is a green light on the motherboard, indicating that it is receiving power, but absolutely nothing happens when the power switch is pressed.
The problem is not the switch itself. I have a switch I use for testing that connects directly to the pins on the motherboard without wires. The same switch is connected to the board in and out of the case.
I'm using 13 of the brass-colored stand-offs that came with the case. The motherboard is screwed to them with screws that came with the motherboard.
The I/O shield that came with the motherboard is in place.
No drives or fans (aside from the CPU fans) are connected to the motherboard in either location.
Here are my build components:
- Motherboard: ASUS KGPE-D16
- CPU1: AMD Opteron 6320 8-core
- CPU2: AMD Opteron 6320 8-core
- RAM: Crucial 8GB 240-Pin DDR3 SDRAM ECC (x4)
- PSU: SeaSonic X-SERIES X-1050 1050W
- CASE: Rosewill THOR V2-White Edition
