Problem with PCI card

Hi friends i am facing problem with my system. It worked fine when i have not installed PCI-1710hg card and after installing it worked for some time later its mother-board stopped working. It happened twice ( two system mother-boards are not working ) So Please suggest me is it due to PCI card or ??

This thing?
Seems it has no CE or UL compliance. Sounds like some test board that might cause a lot of troubles indeed.

Does this card use an external power supply? Perhaps the power supply you’re using isn’t up to the task.
