HP notebook computers Quality and workmanship problems pavilion tx 2000 Internet

HP touchscreen pavilion tx2000 is full of quality issues and HP customer service does not do anything to help resolve it. I bought 2 computers...fancy ones i thought. One has semi circular screen crack, wireless lan quit working, overheats and goes in blue screen thermal shutdown in a couple of hours. Second one has similar problems and inaddition to them, keys get stuck. Both are unpredictable. All these issues started cropping up 14 months in to ownership and I wish I had bought extended warranty. We take such care of them and they are in office environment or home office desk. I can not use touch screen pen consistently so we have not used this feature since early ownership. HP customer service is polite but useless. Please think before yo buy HP....hardly professional units.
