Could it have been caused by the graphics card or the high speed serial port seeing as it was working before then. is that the graphics card that was on amibench as i remember him saying his machine had died .
It could be the drivers for the graphics card are playing up and causing random reboots or your hard drive could be playing up, what drivers are you using are they the ones that came with the card as they might be to old for your operating system.what os are you using 3.1 or 3.5 or 3.9. only thing i can think of is its a software problem caused by the graphics card software. :-?
