The oldest laptop we had W10 on (the laptop was then stolen) was a dual core 32 bit Intel in a Dell e1505 with 1GB RAM and 120GB SSD. It would boot in 35 seconds showing the Chrome web page loaded with Yahoo.com. To me this was proof that W10 could run on not only dual core but some really low end hardware well.
Now about your system. We know that the 350 and 450 AMD boards can be cranky for a lot of reasons. Most of the time it's an outdated BIOS or incompatible RAM.
Be sure those areas are addressed.
I recently built a desktop rig for a family member that now freezes regularly requiring a restart to recover. I've been told that Windows 10 64-bit doesn't always play well with dual core processors. Anyone know if this is true? I see where Ryzen 3's have dropped in price recently but I'd like to get a consensus before I rush into an upgrade. The point was to build a basic general purpose desktop at a low cost for web browsing, email, personal finance, etc. Here are the main components of the build:
cpu: AMD A6-9500 dual core processor w/ Radeon R5 integrated graphics
mobo: MSI B450M Pro-VDH, socket AM4
RAM: Geil EVO Potenza 8GB (2x4GB) DDR4-2400
SSD: Inland Basic 128GB M.2 2280 (for OS only)
