I had an old PC from 2011 that shut down faster than my new PC (old PC had Windows 10 on it). I recently built a gaming PC and noticed it takes 3-5 minutes for it to shut down and about 30 seconds to start up. I don't really have many apps running in the background. I disabled fast start up and tried a few terminal commands but no luck. I play games with Steam and battle.net but turn them off before shutting down.
