Samsung 970 Plus Drive Slow in W10 But Proper Speed in SAFEMODE

Good day,

I have Alienware R4 17 laptop and just upgraded to NVME Samsung 970 Plus. Speeds from CrystalDiskMark 6 are 2300Mb/s vs expected 3500Mb/s in NORMAL Windows environment. All Read/Write speeds are proportionately slow.

When I run CrystalDiskMark 6 in SAFEMODE I observe expected speed of 3500Mb/s. I conclude that something is interfering with ssd speed while in Windows. Whatever it is, is DISABLED when booting to SAFEMODE.

Question is HOW do I find the offending software or driver and get expected speed of 3500Mb/s in normal environment of Windows 10?
