Lately my pc has been doing this weird thing. It would shut down without notice and quit me out of gaming or working. Its sad because then I cant turn it on and need to wait for it to randomly power on by itself. No later than a month ago I got a new Corsair power supply which is 750 watts. Maybe about a week ago I also got my new GPU. Which is when I saw this happening BUT I haven't started any heavy gaming until I got my new GPU so it is very confusing. I have tried restoring my BIOS, turned the windows restart feature off, and even looked at my audio and video drivers to keep them up to date. Its very upsetting. I get perfectly normal temps as well. For instance on my CPU I get around 40 degrees idle and about 55-60 degrees under heavy load like gaming. My GPU goes up to 70-82 degrees when gaming and the minute I close out the GPU drops down to 35-50 degrees which is perfectly normal. I checked my event viewer and found out I was getting a Kernel Power Error 41. I am really doubting that there is something wrong with my GPU or PSU because both are working fine and as they should be. As well for my CPU.







Also here is my specs:

AMD FX 6300 at 3.5 ghz (Not overclocked)

EVGA GTX 760 2gb with ACX Cooling (Also not overclocked)

Gigabyte GA-78LMT-USB3 Motherboard

Corsair CX750M 750 WATT PSU

8GB DDR3 Ram

1 TB HDD

 
Solution
That sounds like power supply load

Downloading the computer is at idle , or close to it . Once you play a game and the grphics card is drawing power then the computer switches off .
Try another psu if you can

Yes everything has great airflow. Also I dont know if this helps but I have a little usb device and my usb mouse both light up even after the pc turns off which is a sign that power is still being sent through the mother board.

Also its mainly happening when I play games. For instance today I left my pc on to download mirrors edge. It didnt shut off untill after about 5 minutes I played the game for.

Update: alright its official its my psu. I tested it with the paperclip method and nothing happened when i powered it up. That means that the power supply is a did and if the powersupply did turn on it would mean its a motherboard issue but thankfully its just the psu. Going to pick one up next week!
