I bought my computer last year in December 2014. It is an ASUS. The model is TP300L series. I'm sorry I hope that is the correct model. I'm not a computer person. Anyways, about a month ago I somehow go a virus in my computer so yesterday a friend of mine told me the best solution would be to re-install Windows 8.1 on my computer. After the windows was re-installed everything works very well again however the I am very disappointed that my touch screen does not work anymore. This is especially frustrating because I can even turn my computer into a tablet. I have no idea what to do and I desperately need help and advice on how to get my touch screen working again like it should. Please, please help and soon. Thank-you so much, Andrea Weber.
