Radeon RX Vega 64 black screen problem

Hello everyone.

 

One month ago I bought brand new Gigabyte Radeon RX Vega 64 card and SilentiumPC Supremo FM2 Gold 750W PSU. Card worked perfect for the first three weeks. One week ago I started have freezes, black screens (this combined with max fan speed of card) or blue screens while gaming. I read somewhere else on this forum this is PSU problem and I need to connect card with two seperate 8-pin cables (which I did) and two different PSU rails, but I don't really know what it means. I also read it can be motherboard problem. Is it possible that my motherboard can not handle 750W?

 

My computer specification:

Motherboard: MSI B250M Mortar

CPU: Intel Core i5 7500

GPU: Gigabyte Radeon RX Vega 64

RAM: Corsair Corsair DDR4 2400MHz CL14

PSU: SilentiumPC Supremo FM2 Gold 750W

 

Thanks for your help.
