i own a tosiba satellite laptop.  not quite sure on the particular type.  It's about 6 months old and it runs windows xp home edition.  My problem occurs in the end of the windows start up process.  Right before windows stops "loading". The "caps lock" key comes on and will not turn off.  Also, the "ctrl" key acts as if it is permanently turned on.  All keys lose function except for those with a control function such as "ctrl+c", "ctrl+v", "ctrl+f", "ctrl+Esc", and so on.  Everything else functions properly.  The other problem is that this phaenomenon only occurs about every other time the computer is turned on.  The only way that i have found to rectify the problem so far is to do a hard shut down and then turn the computer back on and pray that it doesn't happen again.  Simply rebooting widows doesn't solve the problem either. if you do a simple: "start MENU"-"shut down"-"restart", the problem HAPPENS again guaranteed.  I have run several virus scans and even check to see if there were lost drivers or corrupted drivers and nothing came up.  PLEASE HELP, i'm out of ideas.
ThanksLet's find out what machine you have. Download and run Belarc Advisor (free at www.belarc.com) to identifyall the specifics on that machine, including the model number.  the computer is a:

Intel® PRO/Wireless Network Connection 2200BG (802.11b/g)As this is no doubt still under warranty, have you contacted Toshiba?How about tingling a bit with the Ctrl key.

May be its a bit stuck.  i've done everything.  It's nothing physically wrong.  It has to be a corrupted file, virus, or something to that effect.  And i can't get in touch with tosiba.  they have a lovely **cough cough** help response team.it has started doing it when i start up any micorosoft office software.   any idea? i would prefer not to have to reinstall microsoft office.Well that is a HANDY and pertinent bit of info. Cause ----> Effect?

I would uninstall and reinstall just in case something hiccuped during the install. It does not happen otherwise/ And never happened before this?
