I have an older compac laptop, 64 bit with Windows 7
. << From this do you mean you Updated to Windows7 from another O/S ??
Do you worh in a dusty area, or an area that may cause specks of (for example) dust, dirt, food, etc to fall on the keyboard (not unusual) ??
The usual first few ideas are to use a small paint brush or mini broom to clean the keyboard.
Following this you would turn the unit upside-down and Very Gently
tap the area to see if any bits of "rubbish" fall out.
Also just see if you can borrow, or use another mouse for the click problem
If this will not work, please post back, or check if any other answers have been posted to your problem -
Thank You -
