SB95P V2 - same old problem - won't boot

From what I see in this forum I'm not the only one having XPC not willing to boot at the beginning. :crazy:

SB95P V2 XPC barebone
Intel 630 Prescott 3.0GHz 2M L2 800FSB
Transcend DDR3 533 1GB
SATA HDD & DVD-burner
Sapphire ATI X700 256MB video PCI-express x16

That's what inside... No signals at all. All fans are spinning, green led is on next to RAM, no sound, everything seem to be OK but not even close to boot.

Any ideas how it would be possible to get it to boot at least to BIOS?

Thanks ahead ;)
