Sorry for bumping up an old thread. It could be due to inadequate power supply, faulty drivers. No. 1 suspect is the power supply. Will have to spend around 8000 for a good PSU if you wanna run such a card with its power.
I would like to know the model of your power supply(which you used by that time), just for my knowledge.
