I though of the ram is not working as well however, the cpu fan is not spinning either. Fan not spinning may have promp the reboot of the system. Actually the pc not botting is not entire accurate either.. iot boot for 4-5 seconds then reboot, 4-5 second reboot, etc. Cycle won;t stop unless i power off the psu. In casue you are curious, the fan does work because i retransfer everythign back to asrcok and the cpu fan start up fine. Basically what happen on gigatype board is that when i boot, the fan move a few inches, and when it shut off and reboot, the fna spin a little and stop.
btw, i got a pair of pny optima memory ddr2-667, whcih reportly suppose to work fine.
