Gets Black Screen

[jerkyshooter]

I'm using AMD Rx 580 8gb Sapphire Nitro+
I get Black Screen when I test my graphics card on 0xMSAA FurMark. I don't get black screen when I test on 8xMSAA FurMark. Can you please tell me where is the problem in my Graphics Card or driver problem or stuff like that.
Thanks in advance.
I'm waiting for your response.

I reset my Supply and all cables and then reinstall the graphics driver. Finally, I solved my problem.
Thanks
