More thoughts.
Make sure you have a keyboard and mouse plugged in properly, and, preferably, place the mouse in the PS/2 port if you can, at least to start.
Sometimes the BIOS will look "early", prior to video initialization, for the input devices, and get hung up. If the factory default is to "not" allow for USB mouse support, it may need a PS/2 mouse to boot properly the first time, until you change the settings (hopefully
).
It looks as if it only supports USB keyboards, so in that regard, you're kind of stuck. Which also leads me to say the USB mouse should work too, but then again, stranger things have happened.
Also, make sure you have both power connections attached to the motherboard. One in the upper left of your board behind the PS/2 and top USB ports, the other is to the right of the RAM slots.
There may also be an SATA power cable, make sure that is plugged in as well. I didn't see it in the small pictures I've found, but it may have one.
I'd also recommend "not" plugging in the IDE or SATA DVD/CD ROM drive, whatever you have, or the hard drive, and trying to "just" boot the BIOS.
