Start in safe mode. To do this, you need to initiate a PC reboot, click on “f8”, select the option you need from the list, wait for the system to log in, work for some time in it. If the functionality of the OS is not interrupted by an error, then there is a high probability of problems with the drivers. You will have to double-check their status through the device manager, reinstall if necessary. Naturally, do not forget about the possible infection of one of the viruses. You need to install a high-quality antivirus program on your hard drive, activate it and run a full-fledged analysis of the OS.

Find in the list the one after which the failure began to occur. Using the right mouse button, select the delete item. Restart the technique again. As another solution, you can try to roll back Windows to a previous working state. However, for this it is necessary that the user periodically does not forget to create special recovery points. If this is the case, you will need to click on “Start”, enter “System Restore”, follow the link and continue to follow the instructions offered by the program.

Determine if the failure is hardware in nature. If a new device was connected to the computer before the death blue screen appeared, then the problem is most likely in it or the corresponding driver. Check on another PC that the equipment is technically working correctly. Use a different driver version, make sure that the BIOS (UEFI) does not have settings that conflict with the problem equipment. Examine the error description in detail. Sometimes there are not only incomprehensible combinations of numbers and letters, but also a specific process is indicated, during which 0x00000109 failed. Understand what this process is for, remember, you did not change any settings regarding it. For example, it may be the driver of the video card that you recently tried to overclock. Perform a thorough cleaning of the system. Delete all temporary files and programs that are not in use.
