No, it can not happen by itself, unless the card is incorrect designed 
or defect.

Which unfortunate seems to happens as some board designers apparently 
can't read or understand the PCI specs, and since most PC's have 5V 
signaling slots it don't really get tested....

What we have seen before is that the VIO (which in a 3.3V slot should be 
3.3V and 5V slot 5V) and 5V VCC power planes are connected together on 
incorrectly designed PCI expansion boards, resulting in shorting the 
3.3V and 5V power supply together and creating havoc on the net4801....

You're welcome to ship the unit with the PCI board to us and I will 
investigate.


Best Regards,


Soren Kristensen
