That’s the infamous BSOD or blue screen of death. Whenever you encounter this, the cause of the error is normally indicated on the first part of the message. In your case, it seems the problem is with your registry indicated by “REGISTRY_ERROR”. Unfortunately, that’s the most delicate part of the operating system.
Applications store items on the registry for proper functioning that’s why it is very vital to the operating system. At this point, try shutting down your computer for about 30 seconds. You don’t need to unplug it from the power. Just turn it off for awhile. After this, try turning it on again and see if you can get it to boot up.
If you were able to successfully boot the computer, download PC Tools Performance Toolkit. Follow the instructions to download and unpack and then install it. Once installed, start PC Tools then go to “Performance” tab and click “Clean Your Registry”. This will allow PC Tools to diagnose your Windows registry and look for problems.
On the next screen, make sure “Complete Registry Scan” is selected then click “Start Scan”. Wait until the scan is complete. When it is finished, you should see all the items in the registry that needs fixing. Click “Repair”. After this, close PC Tools then restart your computer. See if this works.
On the other hand, if you cannot boot the computer normally, try it using the “Last Known Good Configuration” option. Restart your computer then press F8 on your keyboard before the Windows logo appears. In “Advanced Options Menu”, select “Last Known Good Configuration (your most recent settings that worked)” then hit Enter twice. If this works, follow the instructions above to fix the registry problem.
