Everything on my computer screen is enlarged (windows xp)?

[answerplz]

I have Windows XP, and everything on my screen is enlarged. It looks like when your computer is in safe mode, but i dont think my computer is in safe mode. How do i take my computer out of same mode (if it is in safe mode) or How do i fix this problem?

you may want to right click on your background go to properties see if any settings are enlarged if not try to reset comp and bring up , settings before windows starts to make sure its not in safe mode
