Hi battlecat12345,

Is it happening when you open a certain application?
Have you made any recent hardware changes to the system?

Restart the system to BIOS and keep the system under observation. Check if the system turns off from BIOS as well.

Thanks & Regards

It is not from a certain application but just at random points through out the day. I recently upgraded my graphics card and power supply but this was in June. Finally I put it in the bios for around three hours and it didn't shut off. If you know a solution please help me.

Thanks
Battlecat

✔ Best Answer
I would start looking at the power supply. Random shut-downs are nearly always down to the power supply. The fact that you upgraded the graphics is a good indicator.

It doesn't shut-down when in BIOS because there is very little load on the power supply.

Go to System properties > Startup and Recovery and make sure that Automatically Restart is un-clicked. You should then get a Blue Screen of Death giving you some indication of what the problem is.

If it still shuts down without displaying a Blue Screen of Death or you get a different indication each time then it is almost certainly the power supply.

I'm not getting any sort of blue screen. It just keeps shutting down and restarting.

did you un-click the Automatic Restart as detailed above. If so and it still shuts down then it is most certainly the power supply.

The computer cannot display a BSOD if there is no power to do it.

Hi battlecat,

As rightly suggested by "StuartS", it seems to be an issue with the power supply. Try a good known power supply to isolate the issue.
