Swap them out. If that doesn't work reply back and let me know I'll walk you through checking the BIOS, but if you have a spare mouse or keyboard try that first.

Also unplug the mouse and keyboard. If they are PS2 connections make sure all of the pins are straight. I had a mouse the other day that had never been unplugged at all from the machine and worked fine. Then just stopped, and one of the pins ended up being bent. Don't ask me how it worked before because I can't explain it. Sorry.

I did still the same thing

Are your Keyboard and Mouse USB devices, or PS2?

Might be that USB contoller suffered some damage, or there is some other USB device that might causing problems.

Can you get into the BIOS? If the keyboard works there, the answer is probably that your operating system needs reinstalling.

yes i can get into it. how can i reinstall them if the mouse and keyboard is not working

Try this... it might help.

Unplugg both mouse and keyboard and boot the machine. Hopefully you don't need password (read: working keyboard) to fully boot the machine.

Once it is booted, hit the power button and the PC wil shut down.

Plug back in mouse and keyboard, power on the machine and hope for the best.

In case they are USB (answer the Q, please), then simple plug-out-and-in would do SOMETHING to plug&play service...


Also, you can hit f8 before Windows logo and boot to safe mode.. from there you can look at the logs in Event Viewer, check the device manager, etc.

They are both USB. I will try thst snd let you know. Thanks

the plug in play option did not work so i am going to try the safe mode option to see if that will shed some light. I did not think of that one.

OK - try this in case drivers became corrupted during power-outage:

• Make sure keyboard and mouse are plugged in
• Go to Device Manger (from Control Panel), and uninstall drivers for the correct mouse and keyboard
• Unplug devices and re-plug (leave for at least 30 secs before re-plugging to allow Windows to fully recognise devices have been removed)
• On re-plugging, Windows should re-install the nesc plug-and-play drivers

Have had this issues a few times over the years, and this generally fixes pronto
