XMP profile are pre-defined memory profiles out of JEDEC standard for which the manufactore means that it “should work” ( e.g. 3600’er RAM is ouf of JEDEC ).
In most cases, and in special if the RAM is mentioned within mainboard-compat.-list these mode make no trouble and users get the benefit of higher RAM speed, but sometime it can cause trouble ( in special if RAM is under extrem load )… but these cause more often a CTD and not a reboot.
HAGS is a “new” GPU scheduler which can be enabled within Windows-Graphics settings. It caused sometime also trouble. For me it works in meanwhile, but with former windows release ( or gpu drivers, who knows 
) I got reboots too… everywhere.
What you can do is also to execute a windows-check ( dism /Online /Cleanup-Image /ScanHealth ; sfc /scannow ).
