Ryzen 3000 processors are designed for DDR4-3200 speeds. See if you RAM is stable at that speed.
I overclocked RAMM to 3200, 3600, 3800 using DRAM Calculator Ryzen 1.7.0 By 1usmus, I tested RAM for 10 hours with MemTest64 ( 0 error ) ... I do not know what to do .. I tried everything
I think the processor is broken
uninstall the current AMD graphics driver
try the graphics driver on windows update
