17 R4, Windows 10, Samsung 970, slow

Question

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?

Thanks

Could be an anti-virus program. But try this. Press the Win key plus the R key. Type in msconfig. Now click on Diagnostic startup. Then restart the system. That will start the system with only the most basic of drivers. Then try running CrystalDiskMark 6. If the speeds look normal then one by one you can start adding programs in the startup until you find the culprit. Time consuming as you have to restart each time but eventually you will find out which program is causing the trouble.

Hello, How do I get it back to the original start up settings after deselecting Diagnostic start? Thanks.
