办公电脑又出问题了，进入桌面先花屏然后蓝屏，再自动重启

Symptoms: Bluescreen or Stop Error 0x0000001E caused by nvlddmkm.sys, or often get a message: “display driver nvlddmkm.sys stopped responding and has successfully recovered“.

Solution: Replace the nvlddmkm.sys file with a newer version

This is a well-known fix for the issue.
During the installation of most graphic drivers in Windows 8/7/8.1/Vista, an old version of nvlddmkm.sys is copied into C:\Windows\System32\Drivers and not the current one in the install. As a result the new drivers are attempting to access the file dated 2006 instead of 2010.

SOLUTION!!

Step 1: Download and install the latest graphic driver.

Step 2: Then go to C:\Windows\System32\Drivers and rename "nvlddmkm.sys" to "nvlddmkm.sys.old".

Step 3: Go to nvidia directory (usually in C:\Nvidia or C:\drvvganVidia) and find the file nvlddmkm.sy_.

Step 4: Copy the file to your Desktop directory.

Step 5: Open cmd.exe by going to Start -> type cmd in the search box and hit enter.

Step 6: Change the directory to Desktop by typing "chdir Desktop".

Step 7: Then, type "EXPAND.EXE nvlddmkm.sy_ nvlddmkm.sys". Or,
"expand -r nvlddmkm.sy_ nvlddmkm.sys".

Step 8: When the expansion is complete, copy the new nvlddmkm.sys from your Desktop to C:\Windows\System32\Drivers

Step 9: Restart your computer and the problem should be resolved.

Good luck
