I have Dell inspiron 1525, with intel dual core processor, 2 gb ram and company loaded vista home basic, which has been updated. Since one when I start my system and try to use any of the appications like ms office, a popup message telling that my ctrl key is pressed even though it is not. After repeated logg off and loggin (not shuting and restarting), iam able to circumvent the problem. I request you all for a possible solution to this. Because of some impt data i donat want to formatt it and reload the os. I have avira antivirus which is uptodate. Please help me.
