I dont want to further confuse you at all here,but is this a proprietory machine (dell,compaq,hp,gateway)?
Was this a propritory machine with a new mainboard or cpu?
What bios version are ya running(usually tells at post on top)?
Have you tried to update the bios and if so was it a modded bios or beta version?
Please post bios type and version.give me exact modle number of your board and i will do some research:D
