I am glad to know that the issue has been fixed. However, consider running ePSA on your laptop to ensure none of the hardware component is failing. Inspiron N5050 is equipped with Dell ePSA (Enhanced Pre-boot System Assessment). Dell ePSA can run a thorough test on the hardware components in your computer to ensure they are functional.
To run ePSA:
1. Tap F12 during startup.
2. Select Diagnostics.
3. The ePSA starts running the quick test without waiting for user input.
4. Tap the Esc key.
5. Select one hardware component at a time.
6. Click "Thorough" radio button at the bottom.
7. Click "Run Tests".
8. Repeat this process for each hardware component.
If the test returns any error code, please reply with the same.
