Sounds to me like a graphics card issue. What I suggest you do is to go to Control Panel and then to Device Manager. Then do the following.
- Click the "+" sign to the left of "Display Adapter" and then right click the name of the device and choose "Uninstall" and confirm when you see the prompt.
- Next, right click the name of the computer at the top of the tree of devices and choose "Scan For Hardware Changes". This will reinstall the display adapter.
- Close Device Manager and then see if it makes any difference.
If you don't see any improvement, check to see if there are new drivers available for the graphics card.
As regards your second question, a script is a set of instructions which will perform some function or other on a web page. Unfortunately, there's no clue as to what exactly that will be.
I would advise you to switch to another browser, either Google Chrome, or Mozilla Firefox. I'd recommend Firefox since I use it myself and you can enhance Firefox in more ways that you can with Google Chrome. See this article: Mozilla Firefox features
You can download Firefox from the same page (green button top left).
