Keyboard is psycho, typing different letters each time a key is hit in different programs.

Is your shift key stuck in the down position? Try pressing it a few times to release the key.

Try system restore. Go to START>ACCESSORIES>SYSTEM TOOLS>SYSTEM RESTORE>CHOOSE PREVIOUS RESTORE DATES. Use other restore dates if needed.

If your laptop keyboard types wrong characters, it is rather a software issue than an hardware one. This can happen if you accidentally press certain keys on your keyboard, which enable a certain kind of function.
Try the following steps in case your laptop keyboard displays wrong characters:
1.Go to the control panel option
Click ? 'Regional and Language Services' ? 'Languages' ? 'Details' ? 'Key Settings'
2.Select the option 'Switch Between Input Languages' and click on 'Change Key Sequence'
3.Ensure that all the check boxes are unchecked in this window and do the same for 'Switch to...(Keyboard Type)'
4.Click ?
'Ok' ? 'Ok' ? 'Apply' ? 'Ok'.
This should solve your problem

Examine your keyboard for any build-up of dust, dirt, liquids or other particles that could be causing the keys to type the wrong characters. Allow any loose dirt to fall out by inverting and shaking the keyboard lightly.
Confirm that your keyboard is set to the English language. Go to your control panel and click on the "Regional and Language Options" icon. If the setting appears to be in a foreign language, change it to English/U.S.
Check if your number lock key is on. If so, depress the key to disengage it.
Run a character key test by using the Microsoft Keyboard Diagnostics (MSKEY) program. While in the MSKEY program, hit several keys to make certain that they are the same keys that are identified in the MSKEY window. To start MSKEY in Windows Vista, select "All Programs>>Accessories>>Run" from the Start menu. Type "mskey" in the box and depress the "OK" button. Start MSKEY In Windows XP by clicking on "Run" from the Start menu. Type "mskey" in the Open box, then hit "OK." Depress either "PS/2" or "USB" to apply it to your type of keyboard hookup. MSKEY software is only available with Microsoft IntelliType version 1.1 or later.
Remember to clean your keyboard regularly to keep it free of dust and debris.
Don't disassemble the keyboard because it may affect the validity of your manufacturer warranty!

Otherwise use the onscreen keyboard by start-all program--acessories--accessability--onscreen keyboard

Plug your keyboard into another computer. If the keyboard works, then the port on your original computer may not be working.

You're hitting SHIFT and CTRL -- which changes the keyboard input method, i.e., for French keyboard, or for DVORAK keyboard, or for Scandinavian keyboard.

Access CONTROL PANEL, and use REGIONAL settings to "uninstall" all keyboard-layouts that you _never_ use.

Hold the Fn key then hit F11. This toggles the numeric nubers to letters and vice versa.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
