First thing is to determine if it is actually the monitor and not your video card. Try downloading the latest drivers for your video card and monitor and see if it clears it up if not I would try another monitor on your computer and see if it still does it on the other monitor,if so then its the video card that's causing the lights(you already tried the latest driver so its probably gone bad try contacting the maker and see if they will replace it if your warenty is still good(sometimes they will replace it anyway). if not then its probably gonna mean buying another monitor(is it a crt or a flat screen?) if its a crt or a big heavy deep cased monitor sometimes when the capacitors are going out you can hit the side of the monitor case (not too hard) and see if it changes anything. If you see any changes in the picture when you hit the side of the crt monitor that's probably the problem and you will need to buy a new one most likely because it would be more expensive to fix it.(hitting a flat screen monitor isn't a good idea though).
cursor
Computer mouse
The blinking symbol on a computer screen, often referred to as a cursor or text insertion point, indicates where text will appear when you type. This blinking icon, usually a vertical line or block, signals to users that they can begin entering data. It helps users keep track of their position in text fields or documents. The blinking effect draws attention to the current input location, making it easier to edit or add text.
A blinking object to indicate where to type is called a cursor. The mouse pointer is also called a cursor.

The area with the screen saver and all of those little icons is the desktop.
This depends on the screen type, the screen size, and also the computer's power. For example; a low power computer may use 200watts, where a high power gaming setup might use 800watts. A screen could use as little as 5watts, if it is a small LCD screen, while a big CRT monitor might use 200watts. Your screen should tell you it's power usage, as should your computer, if you examine the power supply.
