Windows 10: PC freezes completely when gaming. Have to switch off at power button.

Having a bit of a problem latel. Sometimes when playing games, usually about 5-10 mins in, my PC freezes completely. No inputs work(keyboard or mouse), all sound stops, image freezes on screen, cant use ctrl+alt+del and I have to turn it off by holding power button down. Doesnt always happen. Was fine playing Destiny 2 for several hours without crash but had 4 today. Updated Windows and GfX drivers recently. I am not really tech savvy at all. Just want the PC working again. Pls help

:)

 

Complete Freeze - Kernel-Power, Event ID 41, Task 63


Managed to solve this.

Seems like I had a couple issues. The power supply was on the fritz and C-States needed to be turned off in the bios.

I went through all the steps listed on this thread by @mileskb
Windows 10 freezes randomly

I did change some of the power management settings in windows, but I had tried that before without results. It might have been a combination of C-States and power management.

 

PC doesn't power down after holding power button for 4 seconds

The power button on a PC is temporary push switch. It makes contact as long as you hold the button down. Quick press and release triggers a smart relay on the MB to turn on or off, depending on default or OS state, such as cold on, sleep on, turn off, sleep off, etc. Holding the button down for a long time is a default hardware power kill switch. If it's not working, suspect the MB. Reset the BIOS is a good suggestion, but prolly won't work.

 

Sticky power button.

I had (still have actually) a Thermaltake Xaser case that had a power button that would get stuck. The plastic housing would get wedged sideways and hold the button down. I eventually just learned where/how to press it so it wouldn't get stuck.

If you don't mind chopping it up, you could try replacing it with something like a vandal resistant switch or a military switch. Any kind of momentary switch would do. Drill the appropriate sized hole and screw it in.
