Based on your tests, I wonder, does the system beep if you try booting it up without memory? If it does, we could begin the diagnosis/troubleshooting by suggesting to have the system assembled with the bacic components, only.
* Please, ensure you wear an anti-ESD bracelet on an anti-ESD surface (click here).
* A basic computer configuration would consist of the following: keyboard, mouse, processor, memory (see the note below), hard drive, DVD-ROM, video card, and monitor. No other add-in should be installed.
Nope, when I assembled it out of the case I tried powering it up without memory. No response whatsoever. IIRC there's a beep code for missing/bad memory so that's pretty bad. The board is, AFAICT, completely unresponsive.
If you do get beeps when trying booting the system up without memory, it means the following can still be tried out:
1. Clear the CMOS as outlined here:
2. Perform BIOS Recovery using the most current .bio file (click here).
