Why does my motherboard not work unless I manually clear the CMOS before booting?

I have this motherboard that’s driving me crazy. It doesn’t start, no beeps, no video, power supply is ok, coolers, hard drive start fine, I’ve tested all components in another PC separately and they all worked fine including RAM.

The funny thing is: when I clear CMOS with the jumper on the motherboard, works just fine, of course with the CMOS error displayed and pressing F1 to continue. If I reset on turn it off, it doesn’t work anymore.

Asus A8N-SLI SE / Processor Athlon 64 / Chipset NVidia nForce 4 SLI/ 512Ram DDR / 120GB HDD.

Please HELP!!!
Thanks in advance!
