Keyboard goes crazy!

About once a day, especially when I'm typing a sizeable document, my keyboard suddenly starts typing characters other than the key I press. It seems to be totally random, except for the numbers and the "a" key. when I close the app, then keyboard goes back to normal. I have run AV on this machine many times & don't get any indication of a virus. Is it just a "buggy" board or a more serious problem?

Swap it with a different keyboard to know if kb or not is causing the problem.  If other kb gives same problem, then you know its software not hardware problem

might be due to corrupted registry try this
http://support.microsoft.com/?kbid=822705

Also check in device manger in control panel that the device is working properly and not conflicting with other devices.

Try uninstalling  drivers  of keyboard from devicemanger  or uninstall if you have installed any keyboard driver software .

Reinstall drivers

Also if above doesnt work in the command type sfc/all and insert windows xp cd


If above all fail then boot windows xp cd from bios and in setup press R for reparing system files

A left field possibility. How much RAM do you have?
Does your mouse cursor sometimes act in a demented fashion?
I note that it's when you're working on a large document. This could indicate a shortage of RAM. You're working with virtual memory which isn't fast enough to keep up with your typing.

Also try my perennial favorite for mysterious problems:
Run System File Checker to restore and repair all Windows files.
Start/Run/ Type "sfc /scannow" without the quotes.
Click OK.
Have your Windows CD ready to insert if prompted when repair is necessary.

This is worth doing every couple of weeks as part of your regular maintenance.

I swapped for another keyboard and the same thing happen. My IT guy says it may be a virus. I reun AV scan every day  & it shows no infection .
And I ran sfc. It didn't ask for the CD.
So it has to be a software issue. I just am perplexed as to what causes it.

I think a Repair installation of XP is the next step.

Did you try deb9's suggestion of removing keyboard drivers? XP should auto-re-install them on reboot.

Does this happen in Safe Mode?

I have never tried to see if it happens in Safe Mode. I seldom get into Safe Mode.

I should have clarified that. :o)
If you start in Safe Mode (tap F8 repeatedly after initial boot to bring up the choices) and this doesn't happen then you've narrowed the problem down somewhat.
Safe Mode disables everything that's not needed to run Windows. Auto loading programs aren't allowed to run and all but the most basic drivers are disabled.
If the problem still occurs then, another clean installation seems a more likely solution.

There's a full explanation of Safe Mode for XP here:

Sorry for the long delay. I think sfc cured my keyboard issues. I haven't seen it come back since.
