Hello lacole_a,
I understand that your browsers will not open.
When you click on the browsers what happens?
Do they flash do they move down to the bottom of the screen.
How long has this been happening?
Do a hard reset.
Turn the computer off.
Remove the power cable and the battery.
Hold down the power button for 15 sec while booth power sources are removed.
This should reset the hardware in the computer.
Let me know how everything goes.
