Ubuntu shuts down randomly. On restart I see the hd light but monitor is off. Computer is able to restart after about 30mins. I don't see any useful information in logs sylog,dmesg etc.

I am using a desktop computer. Around 2 years old.

    Edit your question to include the terminal output of grep -i -e temp -e therm /var/log/syslog* and I'll take a look. Is this a laptop or desktop? How old? – heynnema Aug 6 '17 at 17:42
  • @heynnema on few occasions on restart the system light is on but monitor light is off – Parshi Aug 13 '17 at 18:02
  • Is this a laptop or desktop? If desktop, does your video card have a fan on it? If so, is it working? When you say that the video monitor light is off, do you mean the power light? Is this the same light that indicates that it's in energy saving mode? What color is the light? What kind of video card? – heynnema Aug 13 '17 at 19:40
  • It's a desktop. Does not have a video card, built in. Monitor light is same as when system is off(orange, blue when it's on). – Parshi Aug 14 '17 at 2:59
  • Just to confirm... the video is built into the motherboard... sometimes the light on the monitor is off... not orange and not blue,,, but off. Why can't the computer be rebooted before 30 minutes? Have you checked to make sure that you have the latest BIOS in your motherboard? How much RAM? Lets look at grep -i mem /var/log/syslog* and sudo lshw -C memory. – heynnema Aug 14 '17 at 3:07
