Help! Windows lag during downloads

[Flamewolf00]

Starting off with the specs before getting into the issue

 

I7-9700k

Gigabyte Z390 Aorus Pro

Corsair RMx1000

32gb corsair vengance 3000

Gigabyte 2080ti waterforceb

(Open loop cpu/gfx)

Samsung SSD 850 evo 250gb boot drive

Intel m.2 660p series 1tb game drive

 

I recently factory reset windows 10 because of some software somewhere on the system causing a different issue, and since then whenever i download/install a game using a program such as steam or battle.net launcher or origin, my cpu usage sky rockets not from the program itself but on the system process, bumping up to 30% usage and causes everything else on my computer to lag, even moving my mouse is nearly impossible

Its a very apparent issue with the intel m.2 drive, that started only after the wipe, and it doesnt have any affect on the samsung boot drive. I have no idea what the issue but its something between the system process and the m.2 drive.

Any ideas or places to start looking to diagnose?

Did you reinstall all the latest drivers? Using Windows Generic Drivers or outdated Drivers can cause a hit on performance.
