Question GPU Driver causes pc to stutter

[sheeshdude444]

I upgraded from 1060 6gb to 1070 8gb. The pc works fine with the old card, upon installing the new card and after windows installs the driver for the new card. After installation the monitor will show artifact and after restarting.
The pc turns to run slower/laggy. I tried using DDU and it works smooth without the driver. I tried running games even though it is laggy, games works fine with high fps but it lags on desktop. What could be the problem? Software or Hardware?

PC Specs:
i5-9400F
z370 MSI
16gb Ram
650w Corsair (CV650)

I upgraded from GTX 1060 6GB TO GTX 1070 8gb
The pc works perfectly fine before the upgrade. After the upgrade the pc works fine in first few moments but when the windows nvidia driver gets installed, the pc will become stuttery/laggy.
What could be the problem?
Method tried:

• I already tried using DDU
• hard resetting the pc by reinstalling the OS.

Could it be a hardware or software issue?

Specs for reference:
i5-9400F
MSI Z370
16GB Ram
CV650 Corsair

How old is the PSU in your build?

I upgraded from GTX 1060 6GB TO GTX 1070 8gb
I'm assuming the GPU you got later on was used? Used for mining, perhaps?

About 2 years, Yes the gpu I got was used. I have no idea if it was used for mining.
