how to resize my desktop icons??

i was using my computer this morning and it was fine but i put it on sleep for a bit and when i turned it back on my freaking icons were HUGE.. my whole desktop, everything... when i use firefox, everything is huge also... url bar, text, scroll bar on the right.. everything..

i googled and tried finding solutions but i cant seem to fix it. i hold down ctrl and move the mouse scroll bar down and it re sizes the desktop icons but everything is still big.. my clock. everything..

i am using windows 7... noooo clue what to do

better you may re install your os.

 

just press ctrl key on keyboard and then scroll the scroll key on mouse either clockwise or anticlockwise.

 

Do your display driver install/working properly?
