Windows 10: My system is restarting suddenly

I checked event viewer to check what was the cause, it turns out to be this, any help would be appreciated "The computer has rebooted from a bugcheck. The bugcheck was: 0x000000d1 0x00000000c0002081, 0x000000000000000b, 0x0000000000000001, 0xfffff804876e0072. A dump was saved in: C:\WINDOWS\MEMORY.DMP.

Automated Restart of Windows 10 PC

Hello,

If Windows suddenly restarts without warning, or restarts when you try to shut it down, it might be caused by one of several issues. An outdated driver and software conflict are some of the possible reasons. Having said that, we suggest performing
the following steps:

Step 1: Disabling the automatic restart option to view error messages.

Many hardware driver or operating system errors will cause the computer to display a specific error message before stopping the operation or shutting down the computer. However, if the Automatically restart option
is enabled, an error message might not be displayed despite an error taking place. Disable this option to allow the computer to display the error message.
Follow these steps to disable the Automatically restart option:

• 
  In Windows, search for and open View advanced system settings.
  
• 
  Click Settings in the Startup and Recovery section.
  
• Remove the check mark next to Automatically restart under System Failure, then click OK.
• Restart the computer.

Step 2: Checking for failed hardware.

Hardware problems can cause the computer to restart unexpectedly.

Let us know if that worked out for you.

 

System restarts on its own

It all began when I changed my CPU cooling. The system runs fine when I play games, pass 3DMark Vantage with no problem, but when I try to play MP4 files with Media Player Classic it restarts after few minutes. Few times it restarts while idle. I reinstall the Vista but it did not help. The CPU is not overheating (actually is 10 degrees cooler now). Any suggestions?
