The BP6's are *extremely* lockup prone if they don't have very constant stable power (especially under load). Some revisions of the board had known hardware defects. You can read all about that as well as how to modify the board to work better here: http://bp6.gamesquad.net/Q6fix.phtml Your board may be perfectly fine hardware wise though. From my own personal experience -- try changing the power supply in that computer. My BP6 was incredibly unstable (lockup under heavy I/O) until I switched power supplies. YMMV though ...
