I am sorry that you are having an issue with black screens. When the card's fans ramp up to 100% fan speed attributed with a black screen, this indicates that the Over-Current Protection feature on the card is being triggered. This can be caused by one of two things;
1. The card has faulty OCP
2. The Power Supply's 12v rail is fluctuating in voltage
There are some troubleshooting steps we can do to isolate the source of the issue. The first (easiest) method would be to test the card in another system. If the issue follows the card to another system, the issue would likely be with the card.
The second method would be to test another power supply in the system. If the issue goes away with another power supply in the system, the issue is likely the power supply's 12v rail fluctuating in voltage under load.
If you are able to troubleshoot this issue, and you have isolated the issue, please let us know of the results!
