I purchased a Dell Inspiron 3521 nearly a year ago. Few weeks back, my touch screen stopped responding. I, having some basic knowledge in computers, tried everything that i could to make it work again, but sadly, haven't been able to kill an ant in the matter.

My System Specifications are:

Model No: Dell Inspiron 15 - 3521 - Touch

Processor: Intel(R) Core(TM) i5-3337U CPU @1.8Ghz

RAM: 4GB

Operating System: Windows 8.1 64-bit

Video Cards: Intel(R) HD Graphics 4000 & AMD Radeon HD 8730M

Things I've tried already:

1. Refreshing PC back to Windows 8.

2. Updating all drivers and Windows Updates.

3. Updating to Windows 8.1 again.

4. All windows updates again.

5. Rechecked if any driver update was missing today.(No there is no driver updates for me currently)

Additional Details:

1. There is no Tablet PC settings in Control Panel since i refreshed. (Didn't check if it was before, but it sure would have been there.)

2. There is no Tablet PC Components or any similar thing in add features to windows.

3. There is no Touch Screen compliant device in HID or Mice or other Pointing Device in the  device manager.

4. I have the Intel HM77 driver and the latest BIOS running as suggested by the experts on other threads.

If anyone has any other ideas, please help.

Thank You!
