Ok aside from not having the keyboard attached, what could cause this error. I just built this computer and after installing NT I get this error on boot up randomly but often. The motherboard is a p3v4x. 256 megs of NEC 133 ram. Tried a 550 procesor and a 266. On the 266 though, I had to use the 300 setting because it doesnt have an option for 266. any thoughts?
