My HP Pavilion TX 2000 went blank all of a sudden, have u experienced the same?  

I have an HP Pavilion TX2000 touchscreen laptop computer. I have been using this for almost 2 years now. Recently, i would just suddenly go off. I thought it was just because its heating up so fast. I used a laptop blower to solve the problem but to no avail. Then while working the screen would suddenly blank out. Just the other day I put on the computer but it only powers up, I can see power light on but the screen is blank. Now I cannot use my computer anymore, It is not totally dead since I can still see it has power but the screen is blank. Have you encountered the same problem?Any suggestions?Is my computer dead or can I still do something about it?
