I put the system together with a friend, slowly and carefully, taking care to avoid static. But from the beginning, things didn't seem quite right. Every time we added an extra piece of hardware, on power-up the diagnostics board would show an "FF" fault. Only clearing CMOS, and in some cases removing the lithium battery and waiting several minutes (a tip we got from the ASUS forum), would clear the fault and allow the system to post. We immediately contacted ASUS support about this. After several communications with them, we received the following message:
"
Hmm, this is a weird issue.
If the problem still exists, please contact your reseller and let him check the motherboard for you. If it is due to the motherboard fault, the reseller will send it to us through distributor for RMA."
