Question When I install my new GPU the PC lags when I open anything.

[JRigle]

I bought a 4060 to replace my 1660 Super. When I put the 4060 in my PC and open anything it lags the PC bad. I feel like the problem has something to do with the drivers because I used DDU to clean the old drivers off and when the PC restarted Windows it used an old out-of-date driver, I don't have the lag problem but I need a newer driver to play games. Also when I put my 1660 Super back in with the newest drivers everything is fine. I've never had this problem before and everything I see only says to use DDU and I've done that, I've looked at also checked the BIOS to make sure there is nothing in there that needs changing and it looks fine, I've updated my BIOS before I got the GPU because I saw I needed too, I've seen something about enabling hardware accelerated GPU scheduling and I already have that enabled. I'm lost on what to try next. Below are my PC specs. Please help because I have no clue what to do next.

Run DDU again, but disconnect the computer from the internet until you install the new drivers.

I did this and my whole PC still lagged but I used DDU to uninstall drivers again and used the older driver 537.58 and the PC stopped lagging but I'm still getting bad fps in games. I tried driver 546.65 and it restarted my PC during install and took me to a black screen. I'm kind of at a loss and unless someone knows of something else I can do I might have to try to return the card.
