I recently installed W11 updating from W10. My games on Steam ran perfectly. Now, when I try to access a game on Steam, it starts to load, the the computer shuts down completely. I have to turn off power at the power supply then turn it back on to get power back up again. I had also updated my hardware with a new motherboard, CPU and memory at that time that W11 was installed. I suspected maybe the W11 firewall was interfering with the games but I am not sure. Any thoughts as to what the issue may be?
