Computer turns itself off and power light stays on

[vesh88]

Hey guys. The PC I'm on right now has been turning itself off randomly when I am using it. When it does this the power light is still showing, mouse is still lit up usb sytick still lit up etc.
What could be the cause of this and how can I fix this??
Thanks

Is your computer going into hibernation and are your temps OK?

I'm not sure if it's going into hibernation, can it do that randomly by some setting or something?
How can I check the temp I use to have a program but think I got rid of it

Thanks. Here's what speedfan shows

Don't know why the cpu usage is so high!

Temp2 is high. I'm not sure what it is, but open up the side of your case and blow a fan inside, pointed at the motherboard.

Temp2 is high. I'm not sure what it is, but open up the side of your case and blow a fan inside, pointed at the motherboard.

Additionally, crack the case open and blow out all the dust and crap in there. Likely the accumulated PC case dust bunnies could be affecting airflow. Make sure to blow out around the fan area and whatnot.

Use compressed air, or get one of those electric blowers.
