Dota 2 Shutting Down PC at Random

[Besty007]

When playing Dota 2, sometimes it turns off my PC. For no reason. This has happened on different hardware, OS's, drivers etc. My hardware is not overheating or having any faults at all. I play far more demanding games than Dota 2, such as Arma 3, Witcher 3 at max settings + high framerate and never have these games caused my PC to shutdown like this. It's not even a bluescreen, so I have no error code to give you guys. All I get is a black screen and the sound of my PC still running, but totally unusable.

Windows 10 Enterprise 64bit
i7 4790k 4.3Ghz
MSI R9 290x 1100Mhz Core/ 1400Mhz VRAM
8GB Hyper X Fury 1866Mhz RAM
Corsair CX750m PSU

Try this, it may work. You may have a faulty CPU or GPU.

If you have graphics or driver issues, one of the most common fixes is a clean uninstall and removal of your graphics drivers.

To uninstall your drivers, first download and run Display Driver Uninstaller, and follow it's recommendations of booting into safe mode and ect.
(This is a direct download link so you don't grab the wrong version)

You'll download a compressed file called "[Guru3D.com]-DDU.zip"
Right click and choose extract.
Go into the folder and run the DDU v##.##.exe
This will extract more files to this folder.
Run Display Driver Uninstaller.exe
Choose Yes when it asks you to boot into SafeMode.
After you've rebooted into safe mode.
When DDU comes up, if it hasn't selected your GPU manufacturer (Nvidia/AMD/Intel) then choose it from the drop down list
Press the Clean and Restart option
If a window comes up asking to disable the Windows automatic installation of display drivers click yes.

After (or before removing the old drivers, just put the new ones on the desktop or somewhere handy) rebooting back into Windows, manually download the latest drivers from Nvidia or AMD, don't use auto detect, choose you GPU model and OS from the drop down lists.

AMD: http://support.amd.com/en-us/download

Also maybe try lowering the OC on your CPU/GPUs.

Or contacting DOTA support, since this seems specifically like a DOTA issue.

This is across multiple different CPU/GPU configurations, Operating Systems and Drivers.
