ZmaxDP not booting

[ivo]

hi all


i have two problems since two machines i've got fryday just wont boot. power is on. the systems are built. but nothing is printed on screen. nor the keyboard seems to function (ctrl+alt+del). but what is really strange: the mobos do not even give a single POST. i have tried several things: first i tried another graphic card -> nothing. then i tried to boot without ram -> no POSTs either. then i cleared the CMOS took out the batery and checked it. -> nothing too. the only thing that works on the machines: fans, LEDs and the cd slot is opening and closing. first i thought that it would be a BIOS problem but on both barebones...? moreover that both computers behave the same way... so i really do not know what it is. has anyone ever experienced such problems? please let me know if...
