Computer shutting off CPU and CPU fan when I try to game.

by Dudewithacomputer / September 20, 2016 4:26 PM PDT

So I've lately had a problem with my computer where when I try and play games, like Ark or Fallout 4 and the computer CPU and Fan crashes after a minute or two. I just recently replaced the fan hoping to fix the problem but it's still happening. The computer will "shut off", no screen function or fan power, but the lights on the case stay on (however the power button does not function at all). If I unplug the CPU fan and replug it in the computer will start up fine again until I try and play games again. Does anyone know what the problem is? Please help.

Sounds Like Heat To Me

Here, we first open the computer and use compressed air to blow out all the dust from around the processor, heatsink, power supply, and all fans and vents. Then, if the computer has an age at all, or if the it is a home built model, we replace the old thermal paste between heatsink and processor by scraping off the old and applying a new, thin coat.

Of course, making sure you have correct and updated drivers for your graphics card, sound card, and motherboard chipset are also good things to check.

Hope this helps.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
