My mouse has stopped working, please help?

Try another mouse?

Maybe something is interfering with the mouse movement. Did it work last time you booted and did you change anything since?

Sounds like the sensor on the bottom is broken, since other things still function. Not 100% sure though. Also, how did you manage to post this without moving your mouse?

just buy new ;)

Does it use some kind of software? Like Razer Synapse or something?

RIP mouse.

Your computer's battery is dead, try changing its monitor.

Just kidding, turn of your mouse for a few minutes, shut your computer down, unplug it and remove the battery (if any) as well. This would reset your motherboard (or whatever it is) temporary memory, which, if corrupt, may cause weird problems that cannot be explained by normal perspective. That may actually solve the problem.

Strictly speaking, maybe your mouse is broken, or you are using the wrong driver, or just bad luck. But still it is worth a try.

remove the stip of tape on the bottom of your mouse (the one above the optical seonsor).

if there is none, try another mouse.

Sounds crazy that it would work on other computers, but not on yours, did you check the cable? You might have some wire problems there.

Using AMD CCC? Something broke on it for me a few weeks ago, which inadvertantly killed my USB 3.0 drivers (which my mouse was plugged into, giving the illusion of a dead mouse.) So I had to reinstall it. Could be that if you are. If not, pass.

Have you tried if the mouse works in safe mode? Or in BIOS (if it's UEFI)?

Přeinstalovával jsi software k myši nebo ovladač? Ve správci zařízení zkus nejdřív zakázat a potom znovu povolit myš a když to nepomuže tak ovladač ve správci úplně odinstalovat a restartovat.

There's an old prank of putting a sticky note on the bottom of the mouse.

Okay, there's a little update. Reinstalled whole Windows, tried Windows 7 - didn't work, now I'm back on 8.1, still not working. Looks like it might me mobo problem or something. :( Mouse wasn't working even in install thingy.

can you try with a livecd? (ubuntu or something like that...)
if it works it's your windows and not your pc

Punch it a little.
