My keyboard/mouse USB plug was removed from the pc by accident while the pc was loading a video. The computer froze up so I powered it off not knowing at the time the keyboard was unplug. When I restarted the computer the mouse cursor was still frozen on the screen. So I checked the USB port and plugged the keyboard plug back in. I have to log on to get to my desktop and can't since I can't use my keyboard. The keyboard does work because I plugged it into my daughter's computer so it's not the hardware. Help me please!!

1) See if you can restore the computer to a time before the pointer freeze. Look for a [i]restore point[/i] in System Restore, and try to restore the computer to that time. If this works, problem resolved.

2) If System Restore doesn't fix the glitch, type this in the Run menu exactly as shown, copying the spaces:

chkdsk.exe C: /f

then hit [i]Enter[/i]. The computer will analyze the hard drive for errors. Restart the computer, at which time the computer will [i]fix[/i] any errors found by this program.

3) If neither works, you must boot into [i]Safe Mode[/i]. To do this, tap the F8 key as you power-on the computer, and continue tapping F8 until you see the boot screen. One of the options will be:

Last Known Good Configuration (your most recent settings that worked)

Use the keyboard arrows to select this in the menu, then hit [i]Enter[/i].

4) If none of these work, please post back in this thread for further assistance.

I tried to enter in Safe Mode but my keyboard is not responding at all. I can't get into my computer at all. It will boot up to the login screen and my keyboard won't work to type in my password.

tried reconnecting the mouse and keyboard and then restating the PC.

Try Booting in Safe Mode by repeatedly fressing the function key F8.
Go to your device manager find the keyboard and mouse, uninstall the drivers.
Restart the PC, windows will use the generic (default) drivers.

I tried restarting the computer with and without the keyboard/mouse. That's not working at all. I can't boot in safe mode either. The F8 key doesn't do anything.

You could check the BIOS settings if you are able: Switch on USB keyboard support if it isn't enabled.

Remove the power lead and cover from the left hand side of the PC. You should see a round shiny Battery the size of a medium coin. Remembering to ground yourself by putting the back of your hand on the PSU and dont move your feet. Remove it carefully and wait 20 minutes before putting it back in the same way that it was removed. This should set the BIOS back to default settings and re-enable the Keyboard.

If you have remote desktop turned on you can attempt to connect using RDC from your daughters computer.

First try restarting the computer without any mouse or keyboard plugged in. Then shut down the computer and plug in the mouse and keyboard. Try to load into windows.

Unless its a new computer that they left out the ps2 ports try an OLD keyboard. Once you have logged in then you can fool around with drivers.

I tried to use my daughter's keyboard (not a USB port) and it doesn't work with that one either.

by adam

Does the mouse work?

Does the keyboard work in bios?

If it does work in bios try loading the OS disk then when it gets to the selection press R for the recovery console. At the C: type chkdsk /P

Then try to restart.

If the accidental removal has caused a glitch it should only be on the USB port that the plug was removed from.

Try another USB port, then boot the PC.

by mommie27

I tried to use the USB port in the front of the computer and that didn't work either.

by rob miners

your user manual as it may have instructions to clear the CMOS by using the jumper.

by nepenthe0

When you perform a forced shutdown (as happened here), the computer normally runs [i]chkdsk.exe[/i] at the next boot to fix any errors. Alas, this doesn't always fix the corruption that can be caused by a forced shutdown.

I hope there is nothing irreplaceable on the hard drive. If you don't care about the files on the hard drive, and just want your computer to work again, reinstall Windows from the installation/recovery CD.

Alas, you will need to reinstall all your applications, and reconfigure all your settings. Now I get to stand on my soap box and exhort you to invest in [i]imaging[/i] software such as Norton Ghost:

http://tinyurl.com/5s7gw8

Ghost will write an [i]image[/i] file to an external hard drive. Should disaster strike, you can recover your computer with all your applications and settings intact.

How do I get to BIOS if my keyboard isn't working?

by w2ktechman

You can try obtaining a PS2/USB adapter and plug the keyboard into the PS2 port. then you can check out your BIOS settings and press F8 for safe mode(s).

Or, you can pull the side off of the computer and make sure that the USB ports are plugged in. make sure to ground yourself properly.
If there was accidental 'force' when it unplugged the devices, it may have partially unplugged the ports.
If the accidental force tugged on other cables (such as video) this makes sense as well, because the cideo card is partially unplugged (and could easily freeze a system).

If everything is seated well, then try getting a USB PCI card, as your USB ports may have blown.

by mommie27

If I remove the BIOS battery, I was told that I would need a password when I install it back in (when the system tried to boot up).

by nepenthe0

Older computers have a PS-2 connection for keyboard and mouse. The BIOS doesn't power up the USB port during booting, so you can't use a USB keyboard.

Check the back of the computer and look for the original keyboard and mouse ports. If they're the old PS-2 variety, you must purchase a $10 generic PS-2 keyboard or find a USB/PS-2 adapter. The generic keyboards are cheaper than the adapters. You might even have one gathering dust somewhere.

If my hunch be correct, and you find a PS-2 keyboard, you must repeatedly tap the appropriate function key after power-on until you see the BIOS menu. Check your User Guide for the appropriate function key. My Sony utilizes F2, but there are a few variants, so I don't guarantee that F2 is the right one.

P.S. - Are you having fun yet?...

By clearing CMOS you are taking the BIOS back to Default settings. ;)

I was just wondering if this problem was solved. I know it is 4 years later but I have the same problem and I have a custom computer.
