I hoped this would be easy I have just purchased an Asus A7V8X Lan/1394/SATA/gold -uay I have installed it with 1 stick of 2100 512 crucial DDR and am getting a 'system fail CPU test' message. I am using an Athlon Thunderbird 1400 and I have taken it out and it works fine in another PC with an earlier Asus Board. I have cleared the Cmos and tried another battery as I have read that this can be a problem. I am now stuck. I connected the case connectors correctly and double checked I have left the jumpers at default. I hear the Hd start up but once I get the vocal warning thats it. Any help much appreciated.
