How to fix the stop error 0x00000027 in the Rdbss.sys process in Windows :

Safe Mode Startup


The first thing you need to do when you get the blue screen is to turn off the computer. When starting, press F8 before the Windows screen appears. The computer will then boot from the Advanced Options screen, where you can select advanced boot options.

Press the down arrow until “Safe Mode with Network” is enabled and press Enter. If you think you are dealing with a virus that immediately connects to the Internet when you start your computer, simply use “safe mode” instead.

Rdbss.sys BSoD errors can be caused by incompatible software, and if you have recently installed third-party software, this software may be the cause of this error. To solve this problem, we recommend that you uninstall any software you have installed a few days before the problem occurs. The most common cause of BSoD errors is anti-virus, VPN or overclocking software. So, if you use any of these errors, be sure to uninstall it.

In rare cases, newly installed drivers can also lead to a BSoD error. If you have installed new drivers in the past, be sure to remove them or return to the previous version of the driver.

Start your PC only with the necessary hardware.

A useful troubleshooting step in many situations, including BSOD problems, is to boot the computer with the minimum hardware required to run the operating system. If your computer starts successfully, it proves that one of the remote hardware devices caused the STOP message.

Typically, the only hardware required to boot your PC, down to the operating system, includes the motherboard, processor, memory, main hard disk, keyboard, graphics card and monitor.

Check your computer for viruses.


Some viruses can cause a blue death screen, especially those that infect the primary boot record (MBR) or boot sector.

Important : Make sure your antivirus software is completely up to date and configured to scan the MBR and boot sector.
