HP Touchsmart tx2 laptop -- damaged GPU

Good day all,

I currently own an HP Touchsmart tx2 laptop which is currently only about 19 months old. Recently when I tried to start the laptop, the screen stayed blank, all the lights on the laptop flashed on and a couple of the lights kept flashing on and off. I took it to a repair technician who said that the Graphics chip on the motherboard was burnt out and the most convinient option was to buy a new laptop. So here is my problem:
- What is the possiblility of having the chip, or the motherboard replaced?
- If the motherboard is replaced, do I need to buy a new processor or can the current one be used?
- Also, what is the general price of the motherboard and are there any decent website that offer them for sale?
- Lastly, if I do need to get a new laptop, what are the good touch screen laptops (11 inch screens - I like them small - and not an apple product)?

Hope someone can help me out.
