First time poster here so ill keep it nice and simple!

So whats the issue I am having? Well, I'll list them out below as each doesn't seem to be tied to one another but may be?
  1. When unplugging a USB device from my computer case's front USB hub, the PC's wallpaper goes black instantly across both monitors.
  2. All of a sudden my mouse has been noticeably 'floaty'. I am not too sure how else to describe it other than the movements are 100% off for some reason.
I should note these issues both began a week ago and did not occur prior. I could not name a single thing I changed during that time to my setup on the hardware/software end of things other than maybe a graphics driver update like 2 weeks ago? I ended up going through the event viewer seeking some pointers to my issues and nothing notable popped up there other than a bunch of DCOM errors with the NZXT Cam software - I brushed that off and assumed that wasnt the problem as that has been happening for months prior to this happening.

At this stage, im convinced its a hardware issue (either the GPU or Motherboard as other articles have pointed to these two components resulting in similar problems)

Any help or guidance in diagnosing my issue would be greatly appreciated. Thanks!

Tried to enter safe mode and check if the drivers may have played a part in the problem and the same issues were present in safe mode aswell :(

Also, the mouse feeling 'floaty' is clearly visible in BIOS too which is odd...

Does the same thing happen, if you connect/disconnect USB device to rear ports on your pc?
If not, then there's some issue with front USB ports - improperly connected, damaged, shorted out.

Don't quite understand, what "floaty"mouse means here.
Check optical sensor of your mouse. Probably some dust/hairs in there. Clean it. Try a different mouse.

The wallpaper turning black hasnt occurred since last night. Originally this occurred only when using the front USB ports. 90% of the time it would happen on startup and if not on startup ~10 minutes later.

Its hard to explain but thats exactly what it is, the movement feels detached from the actual movements im making with the mouse. I've tried multiple mice & cleaned them thoroughly as well. Wired & wireless mice had the same issue. Its like i've built up muscle memory of how the mouse moved before and the 'floaty' feeling is extremely noticeable now and throwing me off in every game/application im using..

ALSO - tried using the iGPU and the issue with black wallpaper showing up & mouse feeling detached was still there :sad:

Wanted to give an update on the problem I am having. I was looking into anything that I might have changed to my setup prior to the mouse issues happening and one came to my mind.. I bought this cheap USB switch to plug into both my desktop/work laptop and make transitioning between the two seamless. After looking into the specific model I purchased, it seems they are missing some certification and spoke about something in regards to the way electricity traveled across the device and two either the desktop/laptop. At this point im like 99% sure this has something to do with it and im not too sure how to gauge whether or not some of my components were affected by this device. Link to the USB switch I purchased below:

If anyone has any ideas on how I could check on individual components for electrical issues, please throw them my way. Thanks!
