I've had my laptop for about a week now and the touch screen has stopped working last night. The last time I used it I turned it on sleep mode, then when I came back home, it wasn't working anymore. I tried calibrating it and running the troubleshooter, but nothing has helped.

I am using Dell Inspiron 15R. My wireless adapter is Dell Wireless 1702 802.11b/g/n. I am having issues regarding network speed. My drivers are up-to-date.

I have an Studio XPS desktop that won't boot into Windows, startup repair doesn't work, System Restore fails. I have run Dell diagnostics on the system and it's really strange. When i do the Pre-boot System Assessment the Hard Drive DST says Warning - Hard Drive - No Hard Drive Detected.
