Too many IMO. Since you have the Ryzen I'd use the boards at PCMR or
That aside, did you do the usual BIOS updates and drivers from the motherboard maker? I find a lot of folk do not update or rely on Microsoft for drivers.
I put together a cheap editing PC a while back and had an MSI B350 PC Mate motherboard in it. I had some problems with it and after going through another post here and talking to a friend, they suggested I change the board out for a bit of higher end one. My friend recommended that I stick with an MSI or Asus board but to stay away from the B series boards. I'm not entirely sure about what to get since I'm new to building PC's so I wanted to see what anyone would recommend. I'll also say that I'm not looking to do any crazy gaming with this build, mostly some video editing on Hitfilm and Adobe.
Here's a list of the parts that I have:
AMD - Ryzen 5 1600 3.2 GHz 6-Core Processor
MSI - B350 PC MATE ATX AM4
Corsair - Vengeance LPX 8GB (1 x 8 GB) DDR4-3000
ADATA - Ultimate SU800 128 GB 2.5" Solid State Drive
Seagate - Barracuda 2 TB 3.5" 7200RPM Internal Hard Drive
EVGA - GeForce GTX 1050 Ti 4 GB SC GAMING ACX 2.0 Video Card
EVGA - BQ 600 W 80+ Bronze Certified Semi-Modular ATX Power Supply
