Here we go, this is the best way to avoid reinstalling duplicate hardware, which we have all done at one time or other. You need to get to the device manager, start, settings, control panel, system, device manager , hardware, now you will see everything installed in your machine, if you see duplicates for the mouse and keyboard remove them, if no yellow marks in the device manager, uninstall both the keyboard and the mouse, when uou reboot, it will have a pop up in the system taskbar that says, found new hardware, and then it will say installing the software for your new hardware. If this doesn't work then we need to go into the "install hardware" also in the control panel, but that should do it, I am giving you a lot of info, but sometimes we can't find you again until a day or two later so I want you to have all possible inf before you start. Also the easiest way of all is this. If the computer was working yesterday or last week, we can do a system restore thus restoring it to a time when everything was ok and everything was working, this is Start, accessories, system tools, system restore, pick the day from the choices shown on the calander and sit back as it restores your machine back to a working computer, have a good night and good luck,Gym

Unlock keyboard


Well you may have a bigger problem than a locked keyboard. If you tried to shut down all your programs and reboot, and if you could reboot as someone else to see if it it a locked keyboard. By rebooting the keyboard should auto unlock however if your using a wireless keyboard (check your batteries), and finally on this machine there is a problem with using USB keyboards, try to unplug the USB keyboard then waiting 10 seconds, then plug it into a different USB port, this will reset the keyboard in some cases, but it may be necessary for you to reload the keyboard driver. Okay you say how do you do that without the keyboard? Well if your mouse is working go to START>PROGRAMS>ACCESSORIES>ACCESSIBILITY>ON-SCREEN KEYBOARD and use your mouse to reload the USB keyboard driver and see if that fixes your problem.
Good luck!

I have a Dell 2350 PC and none of the usb or other ports work except the monitor


Make sure the batteries are inserted correctly and have charge if applicable
usually located on the underside of the mouse there might be small plastic sticker with a phillips head screw under it rub your fingernail over the top to see if it has a screw
or make sure the usb device is properly inserted for wireless
the usb or Ps2 connection are secure with a dust free connection

or it might be the usb for wireless mouse or lead connecting to the usb port or even a faulty mouse
if this does not fix the problem
Restart you computer tap the f8 key repeatedly to enter safe mode where the only things working will be your keyboard and mouse allowing you an attempt to repair your computer
If done properly the user should get to a screen similar to the below screen.
Select the option for Safe mode command prompt only
Windows Advanced Options Menu
Please select an option:
Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt
Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)
Debugging Mode
Start Windows Normally
Reboot
Return to OS Choices Menu
Use the up and down arrow keys to move the highlight to your choice.
select safe mode
click start control panel administrative tools computer management device manager scroll to mice and other pointing devices you might see a yellow exclamation mark ! or question mark ? or a red x
right click you will need to update the driver
Click start control panel mouse you should see 4 tabs buttons pointers pointer options and hardware under hardware you have options to troubleshoot also you can select properties under driver you will have options to update driver rollback driver or uninstall also
I have found that the best way to adjust your mouse settings is to create a control panel in your bottom toolbar scroll to the bottom of your screen right click you will see an array of options select the toolbar option then select desktop
then you will see the desktop in the bottom toolbar select the 2 arrows >> then all control panel items then select mouse this is in WINDOWS 7
in XP you will have to select the new toolbar option once you have that a browse option select my computer then control panel then a control panel option will be in the bottom toolbar
Click start control panel keyboard hardware make sure you have the right keyboard selected
or you might have uninstall the keyboard then restart your computer then reinstall it and its drivers
click start control panel administrive tools computer management device manager scroll to keyboard you might see a yellow question /exclamation mark ? ! or a red X right click update driver

USB Keyboard and mouse wont work with PS2 KVM with adapter


Have you tried rebooting once it is connected? Not sure if it makes a difference, but I know you can not hook up PS2 peripherals without rebooting.
