[SOLVED] I just upgraded my PC, but since then I have intermittent stuttering and frame drops that also cause the mouse to stutter/freeze when playing games

[DamianG623]

I recently upgraded my system and since then I have been experiencing an issue where games will stutter randomly (not specifically when under a lot of stress either) and the mouse will also lag or just feel wrong and not move when I try to move it. I have even noticed symptoms of this issue, like the funky mouse movement, outside of games at times.
I tried replacing my old PSU, reinstalling everything, and so forth. I believe the issue went away when I booted the system without any non-windows programs running but I cannot be sure because this issue is not present when a game is first loaded usually. I only notice the issue when a game (not necessarily the same game) is loaded for the second or third time, and then every time after that. A restart can usually remedy this until a game is launched a second time as far as I can tell.
Any assistance would be greatly appreciated.

By reinstall everything do you mean you reinstalled Windows? If you changed chipsets this is a mandatory first step.

No I didn't reinstall windows on my SSD, would these issues be present because of that?

That would be a good idea.

Clean install windows 10 with a big upgrade.

How do you recommend I reinstall it? I know settings has a way to "reset" windows but is that sufficient? And also is there a way to keep my files when I do it because the resent option tells me it will remove all of my programs even if I reset with the keep files option.

Backup any important data.

Create a windows 10 bootable usb and boot into it. Format boot drive and reinstall. Then install all programs.

I have not reinstalled windows in a while (since I upgraded to an SSD), does it give the option to overwrite the Windows install on the SSD?

If you format the drive from the installer and then install it will overwrite your old os install.

Oh I didn't know if you meant my SSD boot drive or the USB one, I get what you're saying. Thanks for the help!

As Damian said, Try reinstalling windows 10, That works in most cases. Not always
