i am facing some weird problems. it all started after i unplugged power cable without shutting down the computer.

Currently mouse is not working at all. its not even getting power. However if i connect the mouse to a front usb port, it gets power but nothing happens, not working.

i tried another mouse on the same rear usb port and its working almost fine. whats with this dual behavior? bad mouse(first one)? or did i corrupt my system file?

Note Almost fine - cause, sometimes 1 click resulting in 2 clicks.

keyboard- same as mouse. sometimes 1 keypress = 2/3 press.


keyboard- shift button dont work sometimes. selected texts get copied without clicking copy.

speaker - only beep like sound.

  • A loss of power and not a proper shutdown can certainly cause problems.

  • Many will tell you to spend hours and a lot of effort to fix it. Myself I would save all the personal files and re install quick simple and fixes everything.

Reinstall is the fastest way to fix this and any other hidden problem that may come up later.
