psensor temp recordingmy pc automatically power off while watching videos on chrome. there is an AMD RADEON HD 5450 2gb graphics card installed. this is my pc configuration.

this is my pc configuration.

  • I'd have a look at the cpu temperature (there are apps that do this; glances shows temp of cpu core(s) and my radeon gpu but its resource-hungry; psensor etc are better suited for it) as if it reaches close to threshold (100oC on some) the system will turn off and there is nothing you can do about it. Some cpus slow (really they pause) as they approach threshold-heat, but they'll still turn off with no warning (at head-threshold) – guiverc Feb 15 '18 at 7:19
  • upgrading RAM solves this? – vemuri kalyan Feb 15 '18 at 7:47
  • nope. upgraded cooling is the only thing that will help IF its getting too hot, hence the recommendation to explore this via tools (psensor which does exactly this, or glances which is super easy to use even if resource-heavy). note: excessive heat is a guess based on your description; you'll have to confirm the guess is correct or wrong, but note @Ashwin Geet D'Sa had the same reaction (I hadn't see Ashwin's until I'd posted my comment) – guiverc Feb 15 '18 at 7:51
  • thank you @guiverc. I can confirm by touching the body of CPU that it is the reason. can an air conditioner do any best?btw, psensor records following – vemuri kalyan Feb 15 '18 at 8:45

See to it that your system is not overheated. Usually overheated system automatically turn off.

I'm afraid your PC setup of a single core 2,8Ghz processor with 2GB RAM is below the minimum requirements for Ubuntu Desktop Edition !

I'd suggest using Lubuntu since that is based on Ubuntu LTS but much more lightweight and has very low minimum requirements.

  • is there any differences between them? according to performance. – vemuri kalyan Feb 15 '18 at 8:53
  • yes, Lubuntu is using LXDE instead of gnome3, which performs much better on lower system specs, like yours. – Robert Riedl Feb 15 '18 at 8:55
  • Yes there are differences between them. Underneath the Ubuntu core may be the same, but above that they are different, with different libs etc. LXDE is less resource heavy, needs less memory meaning you'll need swap less etc. all of which can add to heat ... The version of Ubuntu (and its DEsktop) makes a difference; if using Unity you can put it in a low-graphics-mode which will help if using a compatible version.. XFCE too is much lighter than Unity (or GNOME) – guiverc Feb 15 '18 at 8:56

Knowing the amount of resources that Google Chrome requires especially while playing videos, I bet the system was just overloaded. There is no way that amount of RAM and a single core CPU can handle the tasks you have been throwing at it even with the graphics card installed.

  • then there is no way to stop this rather than upgrading my pc. that's it? – vemuri kalyan Feb 15 '18 at 7:02
