My mouse (Hyperx pulse fire haste) keeps disconnecting and sometimes my whole setup except my monitor and pc just shuts down so when im playing a game i cant hear anything nor can i use my keyboard (i think keychron k8) and mouse. Its getting kinda annoying mostly the mouse disconnecting randomly ill try send some videos to show what i mean. Ive tried basically alot of things ive done Scans in cmd, ive updated mouse drivers, uninstalled mouse drivers, diactivated mouse, change the power option in my pc, change power option on my mouse. Atleast thats all i can remember for now, I also have tried using the mouse on a diffirent device and it seems to be working completly fine and when i used a diffirent mouse (razer deathadder essential) it does the same thing.

mouse keeps disconnecting randomly

Thank you so much for the response.
I have tried my best to follow all the steps you listed but none seem to work.
I've ended up with one of my mouse's not being able to connect at all after completing **"Press Start then search Device Manager" which worries me.

I have also tried three different mouse's which all have the same disconnecting problem.

If there’s any other way you can help I would appreciate it a lot.

PS sorry if I’m not making sense I’m beyond confused
