Question Windows 10 Laggy and stuttering.

[BoomerD]

I did a reformat and clean install of Windows 10 this week. Installed onto a freshly formatted HP EX950 1Tb NVMe drive. I've reinstalled all the various motherboard utilities, (sound, LAN, etc) and updated the Intel drivers for wifi and bluetooth.

When surfing, the cursor will disappear and I just get the "bar" that does nothing for a few seconds...then the cursor comes back...for a while. When typing, I can get a word or two ahead of the text that's actually on-screen.
Specs are:
ASRock Z390 Phantom Gaming 4 (IBuyPower OEM board)
I7-9700K stock
EVGA RTX 3070 FTW3 stock
2x8GB RAM stock
Some CoolerMaster AIO 120mm fan cooler

USB devices plugged in:
Brother laser printer
Logitech joystick
Corsair mechanical keyboard with Corsair mouse plugged into that. (USB 3.0 ports)
Beyerdynamic DT880 250 ohm headphones plugged into front headphone jack

Didn't do this before the reformat/reinstall. Was booting previously from a WD HD770 2Tb NVMe drive...and a WD 240Gb SSD. Neither of those installs did this.

What am I missing? What am I doing wrong?
Task Manager shows nothing out of the ordinary.

You might check the Windows Reliability History in Control Panel under the Security and Maintenance section to see if there is something identifiable causing a problem. It probably also wouldn't hurt to check your Windows system and application logs to see if there is something going on there as well.
