I guess it could be that the fans are ineffectual and therefore aren't
cooling satisfactorily so something (but what!) trips to stop the CPUs
(or power supply?) burning up... I think if you have a MS Windows boot
disk and just leave that and it cuts out that that would prove it's a
hardware issue
I've a custom made box with 2 3.x GHz Xeons in on a SE7320SP2 server
board and no problems I know off (fingers crossed!)
