Random shutdowns with no warning or error messages could indicate overheating so buy a can of compressed air and give the inside of the PC case a thorough blowout with it, paying particuar attention to dust build-up on heatsinks, fan housings & RAM modules.

Heat is the most common probability in your case. Install HWMonitor and you will be able to see the different temps in real time and see your improvement after cleaning.
If you have modified or changed anything recently then let us know this as well if there is not significant improvement.

You have to be a little bit crazy to keep you from going insane.

Install HWMonitor anyway, it shows you more than just that, it shows you other temperatures including chipset, GPU, hard drive, more plus it shows you fan speeds and more important is the voltages. You may find that one or more of your voltages are above or below acceptable levels. All voltages need to be within 5% of their nominal levels. You can check these in your BIOS but you can get a truer reading over time from HWMonitor because it shows you current plus min and max levels since launch so you can watch it for a while to see if it becomes a problem if say you open a program or two. If the levels are outside of the acceptable levels, replace the power supply. If there is one or two temps that appear to climb steadily then the dust build up is acting as both an insulator and a block to cool air flowing, so clean it out.

Hi,

If you don’t think that system heats up then it could an software or hardware issue.

Does it shut down while you open any specific programme or application.
If any software does no cause, then you can put you system ON in BIOS for almost 4-5 hours.
In case if system shuts down in BIOS then it has a problem with hardware, if not then for sure that you system has a software issue.
One more thing, please make a notice of lights on system, whether all goes off or not.

Please reply if any of this step works for you.

Regards,
Lou Nemec
