I have had a terrible time with my new computer, constant crashes in really any flavor of ubuntu or mint. I am now on Mint 13, which is better, but just had 2 crashes in 12 hours, one while the machine was locked.

I am starting to think maybe the GPU is the problem, so i wanted to check the temp. I used inxi -F and found the idle temp at 47-48, so a bit high but not necessarily a problem.

I was checking that regularly, because of all the crashes I have had recently, and later when I was using a lot of resources, I found the sensor no longer provides any feedback, I mean, in the readout, the gpu temp is now gone, doesn't appear.

So that worried me, so I used this: sudo service module-init-tools start. And that readout tells me my gpu is 15 degrees celsius, which seems impossible. Its summer here, I have no special stuff on my rig, the gpu doesn't have its own fan, the mobo temp is 35 degrees.

Here is the total output for sensors:

If you have NVidia card then you should type :

nvidia-smi -q -d temperature

it will give Product Name, PCI ID and Temperature.

You can also install psensor:

sudo apt-get install psensor

psensor will show cpu temp and gpu temp in the system tray.

Thank you. I must have some bad hardware to have all these crashes. the nvidia-smi gave me 48 degrees, exactly what i expected it should be. –  RhZ Jul 15 at 5:02
    
You probably mean 'psensor' and not 'psensors' without an 's'. It is "sudo apt-get install psensor" without an 's' to install it. –  JeanFI Aug 2 at 20:33
