If you notice this issue after the recent Windows update or recent hardware changes in your computer? Then remove the hardware and check if you see the error or restore your computer to preview working condition to check if the computer is working fine.

Quick Note: Before making any changes in your computer, I suggest you to create a System Restore point  so that you can restore back your computer to previous working stat if something goes wrong. Perform below troubleshooting steps one by one. After every steps check if the issues is fixed.

Step 1: Faulty RAM (Random access memory).

Let us first diagnose the RAM. Windows 7 includes built-in features to help you identify and diagnose problems with memory. You can run the Windows Memory Diagnostics utility by completing the following steps:

  1. Click Start, type mdsched.exe in the Search box, and then press Enter.
  2. Choose whether to restart the computer and run the tool immediately or schedule the tool to run at the next restart.
  3. Windows Memory Diagnostics runs automatically after the computer restarts and performs a standard memory test automatically. If you want to perform fewer or more tests, press F1, use the Up and Down arrow keys to set the Test Mix as Basic, Standard, or Extended, and then press F10 to apply the desired settings and resume testing.
  4. When testing completed, the computer restarts automatically. You will see the test results when you log on.

Note: that if a computer crashes because of failing memory, and Windows Memory Diagnostics detects this, the system will prompt you to schedule a memory test the next time the computer restarted. In addition, you may have to replace RAM memory to get rid of it.

Step 2: Reboot the computer in Safe mode.

By rebooting your computer in safe mode, we can load only basic drives and default software’s. Observe your computer in safe mode for few moments to make sure computer is not rebooting in safe mode. Moreover, it is only rebooting when it is in normal mode. Usually anti-virus or corrupted graphics drives cause blue screen error. Hence, let us go ahead and reinstall both.

On previous versions of Windows such as Windows 7, at the beginning of the boot, you are able to press the F8 key to access the Advanced Boot Options menu, where you can enable Safe Mode. However, on Windows 10, the F8 key does not work anymore because the start procedure became faster than ever before. However, that does not mean that Windows 10 has no Safe Mode. It is just that to get to it you have to follow other procedures from this link: Learn how to reboot your computer in safe mode.
