Hey, I have a new system, arous master x570, ryzen 3950x, 64 gig corsair vengenace 2666 ram (4x16), windows 10 installed on Samsung EVO PLUS 500 Nvme. Coming from intel I'm used to 10 second boot times. It now takes about two minutes! I don't know a lot about overclocking or BIOS settings. I did check if I could disable CSM support but that option has a little star on it and I can't disable it.
I have the same issue as previous posters where the arous spalsh screen turns up, goes away, reboots and then loads windows. Usually takes around 2 minutes.
Anything I could try? Like I said, I really don't know much but turning to the internet since the shop that built my computer isn't much help at the moment. I'm running BIOS f11.
