Why is my computer screen massive?

Look at the sticker at the bottom of your laptop. What is your model number? Please leave an update of that or a comment or none can 100% help you.

Hi, Did you get a "Drivers CD"with your computer? You can find the intel graphics drivers in there,
Never ever uninstall anything related to graphics, it will mess up your display,
If you don't have a cd with the drivers, maybe you will have luck downloading it from here,

I'm sure your answers right, but i have no clue what any of that means

I think someone sneaked into your house and stole your small screen and replaced it with a big screen:-) .perhaps you used the wrong term and mean the icons and text are bigger. Click the start button and type Windows Update. Then run it and check for updates. Hopefully, it will reinstall your grpahics driver.

Well you uninstalled the software that handles your graphics card. Without it windows reverts to the simplest 800x600 vga display that you would normally only see if you booted your computer into safe mode. If you ever want to see higher resolution graphics than atari 2600's are capable of you have to reinstall the intel drivers. Reboot your computer and have windows detect your video card and put the driver files back. Hopefully windows will find the driver software in its cabinets, if it can't find intel drivers on your hard drive you may have to get them online. Or maybe you have a cd/dvd driver disc for your video card

You could try a system restore to just before you uninstalled it.
