Loading optimised defaults seems to hinder not help!!! in Processors, Motherboards and Memory Posted May 3, 2006 thanks for the quick reply. i am sure it is not the ballistix i mem tested them for 24 hours about a week a go and got no errors. i tested them at 250mhz 3-3-3-8 1t. so i'm sure it's not them. i can try different mem but im 99% sure that isn't the prob. when i boot i get 3 diaognostic lights show up, with the 4th one flashing every 2 seconds, this sequence continues for about 10 seconds then the lights go out 3,2,1 and then i get a long beep and the 1 light remains on and the systems hangs.
