Keyboard/Mouse Freezes System Sporadically

My system works fine and then it will not recognize either my mouse or keyboard so the system is hung. A hard boot resolves it temporarily. I can see no pattern on when it freezes, different times of day/eve, when left for a while, when in use, no specific application causes it. When I hard-boot back up, I get a double-beeping sound, and I briefly see "Keyboard error" on the screen and then it boots to XP start-up like usual. The keyboard & mouse came with the Dell Dimension system (using XP SP2) and has been working fine for a few years. Problem only started in the last two weeks since I moved. Only difference has been I've gone to a wireless router. A friend says that should have NO bearing on this. I have gone to Logitech's website and installed the newest driver, and checked the batteries on the mouse. "Dell by Logitech cordless Keyboard & Mouse (P/N 851687-0001) I'd really appreciate any suggestions since it's pretty frustrating having the system hang every now and then. At first it was about 2 times per day. Now it's about 6 times per day. I work from home and use Skype as my only phone too so it's doubly-worse. Hoping someone here knows a trick - thx!

    Dhx a mint for the reply bryan26. Were your keyboard & mouse cordless AND were you on a wireless router? (=

  • karen788 Sep 18, 2007

    thx a mint for the quick reply - I guess I'll have to get another cordless set or get a 75' Internet cable. At least the workaround is better than not having it working - much appreciated.

    I've been wrangling with this problem in a classroom with over 30 Dell Dimension 9100s. At first it was just the Dell-brand mouse not functioning (so far, 25% of the mice have been replaced with Logitechs). But I have been seeing your exact problem (keyboard & mouse hanging the minute the XP login screen appears).

    I ran across a forum where one user found the cause to be a bad DIMM. My "Dells from Hell" have had other problems (OS missing a .DLL file, the Blue Screen Of Death) where I had to either reseat or replace DIMMs. I'm going to check out the DIMMs to see if that fixes it.

    (Ya know, it's strange out of all the different brands our schools get, the Dells give us the biggest problems.)

    wireless logitech mouse works sporadically, no obvious of routine cause for it not working, it just freezes. Mostly when i'm online.

    Each time I hit the B key the cursor jumps sporadically to some place else on the screen. Yes, my mouse is wireless. In the first year I did not use the Sony keyboard, but a wireless mouse and keyboard, which was uncomfortable to my fingers. I have now given up the keyboard, but not the wireless mouse.

    my mouse will not connect with the internet

  • Anonymous Aug 09, 2008

    Sometimes the mouse just disappears from the screen. I have no control over where it is or what it is doing, therefore, I can work on nothing. I have unplugged the power source, and plugged it back in and that fixes it, but it is only temporary. I'm also pretty sure that it's not good for the computer to turn in off and on in this fashion.

    i have had the exact same problem with my dell inspiron 530 since i have moved. (with bluetooth mouse and keyboard) except i am on a local lan, no wireless router. the only thing that is new is a panasonic 6.0 mhz phone sitting right next to the computer. the phone was near by before. i'll try moving it. i would hate to get a new mouse and keyboard. weird thing before the move is that the usb flash drives stopped working. then after the move they are working again. so maybe its a USB thing? are those USB mouse and keyboard receivers that fragile?

Wireless routers generally are 2.4 Ghz, as well as the wireless keyboard and mouse. I think there is interference from the router that causes the keyboard and mouse to hang. I had the same problem with my 2.4 Ghz cordless telephones and my new wireless router. Went to 5.8 Ghz telephone and the problem stopped. I'm not sure yet how to work around the keyboard/mouse issue.

Purchase a USB adapter and extension. Connect the USB
receiver to the extension and postion it as close to the mouse and keyboard as possible.

Not sure what is causing the freeze on keyboard/mouse. Must be another device(perhaps another USB device plugged into the same pc) causing intermittant interference with the router. In any case, I changed the batteries, but this didn't help, so I re-loaded the software and it worked again. Seems like a frustrating thing to have to do each time the keys or mice lock up.
Just for the heck of it, I have tried using another USB port for the router. This helped a little bit re-confirming my interference theory possibility.

Hello. Try changing batteries. This has worked TWICE for me. :(

I had a similar problem. For me, whenever i would leave my computer for a while and come back to it, move my mouse, or tap my keyboard my system would freeze. I had an older mouse and keyboard sitting around and plugged them in and never had the problem again. I never even bothered to check if it was the mouse or the keyboard, they are both tucked away anyway. not sure if that helps.

  • bryan26 Sep 18, 2007

    yes they were both cordless and i have a wireless modem as well.

    they we're replaced with other cordless mice and keyboard and I've had no problems since.

    I know this is kind of a non-answer since my solution was not to fix the problem but just to use a different mouse and keyboard.

Computer does not recognize the keyboard,, have windows xp 2002 sp3, and bot the USB keyboard/mouse from crayola. another keyboard that is USB works just fine, so not the port???

Sakar International makes this product.

According to them, your operating system isn't supported, although for the life of me I cannot see why.

Here are the supported operating systems:
System Requirements: --Windows 98SE, ME, 2000, XP or Vista --Mac OS X (10.1 or higher) --One available USB port

Here is the website for the mouse:

And here is the website for the keyboard:

I'm sorry I couldnt help more. This should be resolveable, but the company has no information on how to resolve it.

Problem with KVM switch and Vista

Your problem has nothing to do with the Operating System (Vista), it has something to do with the brand of your computer. I have similar problem before, I have Vista (Dell), but the time I connected another Vista (Sony Vaio), everything worked correctly.

This is what you need to do:

1. You have to make sure that you are using a standard USB keyboard and mouse.

2. Connect first the keyboard and mouse directly to the Vista computer to see if the USB ports of your computer are working properly.

3. You may power cycle the KVM switch by disconnecting it from the computers (including the keyboard and mouse) and leave it disconnected for 2 minutes.

4. Reconnect everything after two minutes and then reboot the computers.

5. Try using different USB keyboard if problem exist after power cycling the KVM switch.

Wireless keyboard doesnt work with switch

once you have switched pc you will need to re-sync the wireless keyboard and mouse with the new pc, because although you have switched pc the keyboard and mouse do not know this. there should be a reset/resync button on the bottom of both the keyboard and mouse
