I wiped out my hard drive a couple days ago. Took the puter to the shop to get it fixed. Now everything is so tiny that I can hardly see what I'm doing!!!

Went to the control panel as was able to make the font larger at the top of the window but the window is still tiny and so is all the content.

HOW DO I MAKE IT BIGGER... LIKE IT USED TO BE?????? I CAN'T SEE ANYTHING!!!
