Why would your computer automatically shut down only "20" minutes after you start it?

Thank you

Your power supply is probably going bad. It gets hot and then shuts down. It might also be a bad power supply fan,

That is the power supply might not be getting hot because of a problem with the power supply but because the fan isn't cooling it properly.

There are possible ways that makes your computer to restart. It could be a worn out power supply that overheats or it could be a "Malicious program" that runs in your computer. Start the computer in CMOS Settings mode, usually by pressing the DEL key or a function key early in startup, then watch for it to restart. If it still restarts, you have a hardware problem. If not, it is a software problem.

For a software problem, look for programs that start automatically and stop them using the Task Manager (control+alt+delete). It should be possible to determine which program is doing it and uninstall it. Apparently, if the problem got worse,  then I suggest you go to your local computer store/service and ask about and possibly get it fixed. There may also just be a setting on the computer that has been set incorrectly, you can also find out if the setting is wrong by the computer store too.

Hope this will help you
