Follow these guidelines to fix this error::
Note: Some of these steps may require you to access Windows via Safe Mode. If that's not possible then skip those steps.
Restart your computer if you haven't already done so. The STOP 0x0000007B blue screen error might be a fluke. Did you just install or make a change to a hard drive controller? If so, there's a good chance that the change you made caused the STOP 0x0000007B error.
Undo the change and test for the 0x7B blue screen error. Depending on what changes you made, some solutions might include:
Remove or reconfigure the newly installed hard drive controller.
Startup with Last Known Good Configuration to undo related registry and driver changes.
Use System Restore to undo recent changes.
Rollback hard drive controller device driver to version prior to your driver update.
Verify that the SCSI chain is correctly terminated, assuming you're using SCSI hard drives in your computer.
Incorrect SCSI termination has been known to cause STOP 0x0000007B errors.
Note: Most home computers don't utilize SCSI hard drives.
Verify that the hard drive is properly installed. An improperly installed hard drive could cause STOP 0x0000007B errors and other issues.
Verify that the hard drive is configured properly in BIOS. The STOP 0x0000007B error could occur if the hard drive settings in BIOS are incorrect.
Scan your computer for viruses. Certain viruses that infect the master boot record (MBR) or boot sector can cause STOP 0x0000007B errors.
Important: Make sure your virus scanning software is updated and configured to scan the MBR and boot sector.
Update the drivers for your hard drive controller. If the drivers to your hard drive controller are outdated,
incorrect, or corrupted then the STOP 0x0000007B error will likely occur.
