Yesterday someone came out and connected my computer to my home network. After they left and I got back to my computer, I found that my keyboard didn’t work. I found that in the device manage my keyboard's icon had an exclamation point next to it, and when I clicked on it it said:"Windows successfully loaded the device driver for this hardware but cannot find the hardware device. (Code 41)". I assumed there was something wrong with my ps2 port, so I went out and bought a usb keyboard. No luck. So far I have tried: removing the driver and reinstalling it, removing the driver, unplugging the keyboard, plugging it in and installing the driver, removing the driver in safe mode (which I can access by the way; the keyboard stops working when the computer starts up.), trying different keyboards, and even removing SP2 (that solved someone on a different forum's problems), and nothings worked so far. I've also tried system restore, but I don’t know for sure if it restored my computer to a time earlier than when it was messed with. The person who connected me to the network is on vacation now, so I cant really contact them. I've scoured the internet (using the onscreen keyboard... yay...), and can't find anything helpful. also i forgot to mention that the buttons on the top of the keyboard work. (buttons specific to the keyboard like media, favorites, volume etc)
Did you recieve CD with your monitor? Put that into ur cdrom and restart ur computer. it worked for me long time ago when I had the same problem. Edit: Did you recieve CD with your monitor? sorry, I mean to say keyboard~!
If you are using PS/2 connectors then try exchanging the ports of Mouse nd Keyboard. Actually I dont have ne idea, I m just trying what can b wrong with your keyboard. or try this; Unplug your keyboard and go to device manager with ur mouse uninstall the keyboard driver. then plug ur keyboard in again. Ur computer will automatically detect the driver.
Flip the keyboard around, remove the screws and check the electric sheet thats in there for signs of liquid spills, etc. If you don't visibly see anything, the keyboard could just be shot. Either send it in for warranty, or replace it. *EDIT* Come to think of it, it could be a problem with your keyboard controller on your motherboard, in that case your board is pooched. Hope this helps~
I've tried uninstalling my drivers all sorts of different ways. Also ive tried multiple keyboards, both usb and ps/2. id realy rather not replace my MB, but if thats the only option...
I'm pulling this out of my ass, but try going into safemode and see if you've got full control of your keyboard.
Yea, ive tried multiple keyboards of both usb and ps/2. And it doesn't work in safe mode (but it does work at startup to get into safe mode).
Salvaging it? No. Get a new board with the same socket so it will fit your current CPU, and make sure it has the appropriate features for your needs.
Check this whole list and I believe you will come out with some result after this TROUBLESHOOTING BASICS As we look into problems with the keyboard,remember the check the obvious first and as with all problem solving procedures,don't be tempted to take shortcuts. Follow these procedures to resolve common keyboard problems.Always keep the keyboard clean and don't set anything on the keys KEYBOARD WILL NOT RESPOND 1st. Restart the computer.This sometimes will resolve a computer that has froze or locked up during the first boot up.Be sure nothing has fallen into the keyboard. 2rd. Look behind the system unit and check to see if the cable is fully inserted into the connector.Check to see if it is in the keyboard connector and not the mouse connector. Shut the computer off and remove the cable from the system unit.Check to see if any pins or connectors have been bent or broken. If all pins and connectors are good.Try connecting another keyboard and restart the computer.If the new keyboard works,replace the old keyboard. CHECK FOR KEYBOARD ERROR IN WINDOWS At times,a stuck key on the keyboard will produce an error message.Notice any keyboard errors that may show on the monitor and look at your computer manual to correct the problem. If the new keyboard should fail as well,check the resource conflicts if your operating system is Windows 98 or Me.Click on Start,Settings,Control Panel,System, and Device Manager Tab in System Properties. Windows displays your devices attached to your PC. Click the plus sign and scan the list for the keyboard. If you notice an exclamation point or a red X beside the keyboard,the keyboard has a problem. Now highlight the keyboard,click the remove button, and click OK in the confirmation window.Close the Device Manager and restart the computer.The operating system will reconfigure the keyboard. WINDOWS DID NOT FIX THE KEYBOARD You have restarted the computer and the keyboard still does not work.Its now possible you have a faulty keyboard port.This may prove true if the second keyboard failed to work on your computer as well. Though it rarely happens,an error message will appear if the keyboard get hot.Stuck keys are also causes of error messages appearing on your monitor at bootup. POOR KEYBOARD PERFORMANCE Keeping the keyboard free from dirt and dust,is essential to good keyboard performance.Liquid spills are common and can be cleaned with a can of compressed air. Your settings in Windows may also be the culprit in poor keyboard performance.To check your keyboard performance,click on Start,Settings, Control Panel,and double click keyboard. On the Speed Tab,you have the option to control the Repeat Delay,Repeat Rate,and the Cursor Blink rate.The Repeat Delay is the delay between the time you press a key and when it responds. The Repeat Rate controls just how fast the key repeats after it begins repeating. Windows give you the ability to control features of your keyboard which will boost its performance, allowing you to perform your tasks quicker. While the keyboard is replaced rather than repaired, it is imperative that you learn troubleshooting steps to correct most keyboard problems.You may have problems with the keyboard late at night and you may need to get it working to complete a document you may need for work.Know how to correct problems and help others that may experience keyboard failure. I found this on the net. I know that you have tried most of the things or probably everything but still to make sure that you have gone through all the solutions.
ive been thru all of those fixes, but thx for putting together the list. as far as getting a new mb goes, how do i find what my socket type is?
Download CPU-Z from here. It will tell you for example, Socket 478, etc. Find a board that matches up with that, and any other features that fit your needs.
