go to device manager, check under IDE ATA/ATAPI controllers to see if they are using AMD driver.
uninstall and delete the driver so it will roll back to the standard sata ahci controller by MS.

Hmm. The macroshaft drivers work ok for me. If the Samsung drivers work use them.

OMG. You and andyliu are my lifesavers RN. I just spent like....a week trying to troubleshoot DPC Latency for Storport.sys and was afraid it was bad memory, faulty M.2 SSD from Samsung, or just a bad motherboard (which I have tried troubleshooting all over the place).

I even wiped my PC 2wice, the second time as a clean CLEAN install with nothing remaining on my other SATA/HDDs/SSDs.

Then, I come across this f*cking rando Forum and get the advice to uninstall AMD's IDE ATA/ATAPI Controller Drivers not being compatible with Samsung SSDs.....and voila, the problem is GONE.


I cannot express the amount of joy and gratitude from you both for this help....sincerely...you both have my thanks.

LOL! It took me a lot more than a week to stumble across the fix for this problem. It was buried in an obscure forum about 9 pages back in a search. Then I searched around here and it was a known issue 2 years ago, except that everyone forgot about it.
