Have just been removing some programmes from my computer, to try and speed things along a bit. I have restarted it, and now all the icons on the desktop look huge, and web pages don't fit on my screen like they did.
your screen is probably set to 800x600 go to control panel-> display-> change resolution and set it to 1024x768. Then go to your graphics card manufacturers site and get the latest driver for your card. (You may need to do this before it will let you change the resolution.)
