Try to press "ctrl key" hold it then press "+ key" ( the one beside the backspace key) simultaneously. The font will increase in size. If you want to return to normal just press the "ctrl key" again and press the " - key" (the key between the "+" and "0 key".
Or you could change the screen display to about "1024 x 768" go to start click it then click settings then click control panel then click display then click settings then changed the screen area sliding control.
Hope this could solve your problem
