Windows 10: Gigabyte B450 Aorus Pro WiFi mobo video

I just bought a Gigabyte B450 Aorus Pro WiFi mobo, and combined it with a Ryzen 3 1200 CPU; 2X8GB Vengence DDR4 RAM;
and a MSI Radeon HD 5450 Direct X 1 GB 64-Bit DDR3 PCIe 2.1 x16 HDCP Ready Video card. But what I get, after post,
and the Windows logo, is a pixeled display of color patterns, that go from black screen to color scramble, and back
and forth, until the monitor shuts down from no signal, while the computer continues to run. The monitors have no
"wake-up" protocol. I have to shut down, and reboot the system. What am I looking for? What SHOULD I be looking for?
Is the card compatible with the CPU, memory, and mobo?

Can't install Windows 10 on a Gigabyte Aorus Pro X399 motherboard

I've built a Threadripper PC using the Gigabyte X399 Aorus Pro motherboard, and I'm trying to install Windows 10 on it.

I used Microsoft's Media Creation Tool in my old PC to create an ISO image, then burnt it to a DVD, and then booted the new PC with it. I should mention that I have set up my X399 PC's hard drives as RAID, in the following way:

• An SATA SSD as an independent volume. This will be my boot volume, where I intend to install Windows.
  
• Two mechanical SATA HDs as RAID 0.
  

Anyway, I boot up the new PC using my Windows 10 DVD... and I reach the step where it says that it needs drivers. The manual of my motherboard says to copy the drivers folder (BootDrv\Hw10) from the included DVD to a thumb drive, so that's what I do.
I plug the thumb drive, and two entries appear, both of which say:

I click on it... but Windows says then that "it hasn't found any new device driver".

I uncheck the "Hide incompatible drivers" checkbox, and a number of new entries appear, one of which is called "AMD-RAID Controller (storport)". I try with that one, but Windows says the same: "no new device drivers found".

I checked at Gigabyte's website (X399 AORUS PRO (rev. 1.0) | Motherboard - GIGABYTE Global), but the newest drivers there are the same ones that I already have. My BIOS is also at the latest (actually, the only) revision.

What do I do now?

MSI Shows Off B450 Tomahawk and B450-A Pro Motherboards

MSI showed off two of its latest socket AM4 motherboards based on AMD's upcoming B450 chipset, the B450 Tomahawk and B450-A Pro. The Tomahawk is slotted in MSI's minimalist yet gamer-grade Arsenal Gaming series, and has a clean look, with a feature-set that doesn't exceed that of the chipset by much. Slick new VRM and chipset heatsink designs which debuted with Intel 300-series Tomahawk boards, make their appearance here. There's just one M.2-22110 slot. The B450-A Pro is part of MSI's mainline motherboard lineup, and targeted at system-integrators, with a similar feature-set to the Tomahawk, though slightly built to a cost.
