So, the last 2 weeks my PC is having some issues. After playing MW3 for 20 minutes my PC starts getting really choppy then will turn off, no power down, just shut off. I have changed my settings from ultra to low, It does not seem to make a difference in if it will stay on or turn off or the chop. The temperature on my MOBO to Proc is about 115 degrees or 43C. I have deleted any program I installed the past 3 weeks. Never had this issue in the past could play for 4 hours and no problem. Anyone else having this issue? Did you fix it or does anyone have any idea on what would be causing it?
Monitor your temperature while gaming.
Use a 3rd party tool such as HWMonitor to record your temperatures on GPU and CPU.
Game first stuttering, and then later on a complete PC shutdown means that the PC is shutting down so as to prevent further damage to the components, whichever component that may be.
