Hello all, wondered if someone could help..

I brought a new Inspiron about a month back. I first had a problem after weeks of owning it where the mouse touchpad just stopped working when I turned it on. I therefore had to re-install the Synaptics touchpad driver, which fixed the problem and my touch screen was still working throughout the whole time (Made it so much easier to fix the issue with the touchpad).

Today I turned my laptop on to find that now my touchscreen doesn't work. After reading many posts I tried to re-install the above driver. Would there be a different driver for the touchscreen and where would I re-download it to fix the issue ???
