Do you mean resize the font on the screen? If you have firefox browser go to tools>options>content and then you will see an area where you can change the font size and style. If you have IE browser, go to tools>internet options>general and at the way bottom you will see a button for fonts, just click on that and modify it. As for audio did you check if your sounds are off? Try right clicking on the sound icon and hit adjust audio properties to see if your sound is accidentally muted. If you don't have a sound icon on the right tray of your computer then just go to start>control panel>sounds, speech and audio devices and from there you can check your sounds. I hope that helps.
