Original system specs are Gigabyte B450M, Sabrent NVMe 500 MB, DDR4 Viper 2666 MHz, TPI wifi card, Win 10 home.
PC worked for about one month. Screen freeze followed by reboot hangs on windows circle of dots. Replaced mother board with ASRock B450M Pro 4. Same problem. Tried booting from USB flash with Win 10 image, same problem. Took to repair shop, they tried SSD and said it was ok, memory sticks ok. People with way more experience than I believe APU is
bad and preventing boot to win 10. Next step is to order another APU to confirm but now price is up another $75. Will AMD
test my APU/ replace APU? All computer parts ordered Dec 28, 2019.
