Disconnect & reconnect your mouse & keyboard, you could have knocked the connectors loose (this is almost certainly the problem if you have the sort of keyboard that you plug your mouse into rather than plugging it directly into the computer).

I think u have pressed the Insert button in your keyboard. Just press the Insert button once more and then it will work properly.

Make sure that your keys are ok! If they work some times and dont other times go to http://housecall.trendmicro.com/ for free anti Virus/trojan/spyware/malware scan! And make sure that your keyboard layout settings are ok!

If you bought it new - Take it back to the store.\n\nIf it is Used and you cant take it back - Check the keyboard connections. Look in the manual on how to remove Keyboard. If you dont have the manual , look it up online they are everywhere. You may need to replace the Keyboard.

Sounds like you have a different keyboard. He messed up the driver for it. If you have windows XP do a system restore and it will fix your problem without losing anything. If not. do a search for drivers for that keyboard.

sounds like the numlock was pressed by mistake. or else, the keyboard setting was changed to a foreign language. either way, reboot the machine. Access the CMOS during POST (F10, Del, or whatever depending on hardware). under extended options, select keyboard, change back to US configuration, save settings, reboot, all is well.

On modern laptops, the keyboard is usually considered an internal USB device. I'm not very knowledgable with PCs but I'd look there first. Perhaps try updating your USB drivers, or reinstall them.\n\nObviously, if you can remember installing any third party software that uses USB or does something to USB, then try uninstalling that first.\n\nGood luck!

Is you keyboard USB - If so check your BIOS for usb legeacy support - if this is enabled - disable it\n\nHave you checked for the most recent BIOS updates for your pc - may have to flash it \n\ngood luck

might be the keyboard, has some dust build up from a little moisture when it was wet, could be corrosio, could be it got on the cable end and it is corroded, I would take it out and check the cable end, if the socket and cable end are shiny, get a new keyboard, you can probably get one on Ebay for about 15$

Sounds like something is wrong with your keyboard.  Try using the ctrl and alt keys on your keyboard that you don't normally use.

It sounds to me like your keyboard needs remapping! Sometimes if you restart Windows, it fixes itself - so try that first. If that's not sorting it out, download the latest version of Messenger (it's now called Windows Live Messenger) from http://messenger.msn.co.uk \n\nIf not, and you've got an old keyboard lying around: plug that in and see if that works. If so, use that for the meantime and get someone to look at your PC.\n\nAnd just one final tip: you might want to ask for McAfee Internet Security Suite for Xmas. Trend Micro's PC-Cillin is useless and if you bought it from PC World they charge rip-off prices on everything.\n\nGood luck!\n\nAyJay

How long has this been going on?  Did you change anything or install any software prior to the problem surfacing?  Have you been surfing any warez sites?\n\nSomething is interfering with your keyboard.  You've done all the right things to date so I'd suggest that you look for something in the system itself.  Some process is messing things up.  When you hold down the shift key, the process eventually dies, releasing the keyboard for normal use.\n\nMy first inclination would be a keystroke logger or other spyware.  Install Spybot Search & Destroy and Windows Defender.  Update the defs and run a full scan with both products.  With luck, you'll find something and can remove it.

Make sure you're tapping (not holding down on) the DEL key the ENTIRE time of startup - don't wait too late.  Also, try a wired PS/2 keyboard if yours is wireless or USB.  Take a look at the resource below.

if it commected by USB, unplug iot and then plug it back up, if it is ps2, then shut down computer, unplug it plug it back uo, and then restart. if it still does not work, probably a bad keyboard

you need to get your keyboard replaced or your motherboard.  It's a short.  Call your manufacturer for more info to get it repaired.
