Could be,  I’ve seen the ribbon cables to IDE disks cause lock ups. I’d  
moved everything but the Mobo and cables to another machine to test, so  
was about to blame the Mobo until I tried the cables as well.
As several people are suffering this could it be the same/similar  
hardware.  Perhaps if everybody, who suffers this problem, could list  
their MOBO, CPU, Video card, etc. a common factor might appear.
