Windows 10: Mouse sensivity going crazy

Hello, i wanted help for a VERY annoying problem on my laptop, my mouse sensivity vent crazy, it happened a year ago while i was playing payday 2 in the middle of the game the sensivity changed and the difference was drastic i mean i noticed it in 1 second so i tried fixing it i've watched TONS of videos there isn't a single one that helps me with my problem and i'm so annoyed by it, i can't play at all.

What i've done to help trying to solve it? Here's every step in 1 and a half years of problems i have this omen laptop from 2 years

- First i turned mouse pointer precision off

- installed Mark C mouse fix

- Changed mouse from a Trust cabled one to a wireless logitech one that the pc ITSELF broke

- Tried everything i could in regedit mouse options

- Tried everything in pc protection settings, ram usage, motherboard usage...

- Disintalling mouse software and reinstalling it

- Tried to update every single driver

- Restoring the pc

- Deleting all my files

Then my hardisk broke.

- So i had to deal with a couple more problems, before that my pc would eventually turn off by itself...won't turn on...etc.

- After that i learned how to deal with it but everytime i solved a problem another one would have came out like: solved half mouse issues then laptop keyboard doesn't work, after that the mouse again, then the software of the mouse...all in an infinite loop.

So i formatted my laptop.

- It seemed to be working and i bought a new mouse after the other one broke Deathadder V2

- Then it changed by itself again...

- So i used the Mark C mouse fix again and it made everything worse

- So i tried to remove it but the DEFAULT file used to remove it didn't! It made it even worse!

And now i'm dealing with this pc afraid of breaking the hardware of the new mouse too unable to play with a DECENT sensibility for gaming.

I'm surprised how nobody couldn't help me...i think the motherboard broke or something.

Please if you read everything could you lend me a hand?

Mouse going like crazy after upgrading to Windows 10

Hello there. Over the last 2 months my mouse is going like crazy! It started after upgrading to win10 and i can't find any solution to the problem. A problem which is really dangerous for my laptop because the mouse not only moves up and down but it also
opens windows, copy things, delete files and folders etc!!! In the start i was just leaving it do his stuff and after some minutes it was ok. But lately it continoues unstopably and the only way to handle it is by forcing my laptop to shut down. Sometimes
it works but sometimes it doesn't!

I have tried to uninstall the drivers but the problem is still there. Any suggestion what the **** am i suppose to do??

 

Device List going crazy

I have Windows 7 Home Premium and the last couple of times I've needed to open my Device Manager the list of devices has been going crazy. It opens, closes, opens, closes, opens, closes and just keeps on doing that. It's kind of hard to find the device
you're looking for when that is going on. Does anyone out there know how to make the list behave and stay open?
