Dead Pixels on my LCD Monitor

There are 3 dots appearing on my screen. I tried to wipe them because I thought they are just dirt, but they are not.
They are appearing on every page that I go to.
They changed colors sometimes, but most of the time they are back.
I am using:
- Acer Aspire Notebook
- ATI Mobility Radeon HD 5470
- Win 7
- 100 GB HDD
- Intel Dual Core
No clue if this is a hardware problem or not. So please let me know if you know any solutions for this.
I am afraid that it will spread all throughout my LCD screen.
Thanks.
