1. Write down both the hexadecimal code for the Stop error (the long number looking something like '0x0000007E') and the text description of the error, if one exists. Also note any additional information the error screen contains about drivers, memory locations or files.
2. Go to Microsoft's Support website (see Resources), enter the hexadecimal code into the search bar at the top and press 'Enter.'

3. Click the 'Troubleshooting a Stop error' result and follow Microsoft's instructions. If no useful results appear, try another search for the error's text description. If you still get nothing, go to the Kadaitcha webpage (see Resources), which contains a comprehensive list of Stop errors and links to instructions on resolving them.
