Guys, I potentially have a problem here:
Recently I've built a completely new rig based on Zen+ for my friend and, due to Zen+'s inability to fully support Windows 7 or 8/8.1, I had to install a fucking Shitdows 10 on his fresh system.
Roughly 14 months have passed since then and, mostly, he's been having it decently, but...today he reported his system started rarely and randomly locking up to the state of absolute unresponsiveness, showing glitches, and black-screening, when he's playing Steam games. He has very good hardware and solid drivers, so no overheating due to hardware or errors due to drivers. It's merely Shitblows 10's fault.
He's mainly only using PC for gaming, so I've suggested for him to try Linux while wrapping Proton around it so that he can continue use Steam easily, but...he never used any OS other than Windows in his entire life, and he's sincerely afraid it might be to hard to get into Linux and he might fuck up a lot.
Guys, Jow Forums, please recommend good/solid and absolutely free (as in - no payment, not as in FOSS necessarily) Linux distros that work well with Steam+Proton and modern AMD hardware such as Zen and Radeon. I want for him to migrate absolutely painlessly by the largest part, so that he could feel almost like he never left Windows 7 at all. Is there such a Linux distro or a desktop environment out there which can provide this to him?
P.S.
I've been eyeing Manjaro, MX, SteamOS, vanilla Ubuntu, Puppy, and Mint, as some distros to recommend for him. Are any of these good candidates to a person who's migrating from Windows and never used Linux even once before in his entire life?
Out of the some listed above, which would be the best option/route for him, considering he's largely only using his PC for gaymen/discord/twitch streaming/onemoo binging/video & image editing, all that shit?
P.P.S.
His current hardware:
AM4 X370 mobo
2700X.
RX 590.
16GB 3200MHz RAM
1TB NVMe PCI-e SSD
512GB Samsung 850 PRO SATA III SSD.
4TB x2 Seagate HDDs.
