Random weird freezes I had as well a while ago .
Woz xtremly annoying ... even a bit tempted to go back to the dark side ... but NO .
It was due to BIOS settings .... maybe if you set the BIOS stuff to very conservative safe settings it´ll run fine ... well prop neva eva frezze again .
Post Scribbles : U confuse me a bit .... u say that U´ve used 2 motherboards but then go on 2 say that the constant is the motherboard ... i.e. only one board used ... or mayB I´m not very bright @ tha moment .. ? ..
