Hi, I tried turning on my secondary desktop after not using it for a few months, and it would not stay on. When I press the power button. sometimes it will turn on right away or take a minute or two but it will turn on. At this point, I can usually get into the bios and change things around and save. However, once I get to logging in an account the computer will just shut off. It doesn't always do it at the same time. sometimes when it's booting up it turns off and a few times I've gotten as far as the profile loading before turning off. I think it's an issue with the power supply but not completely sure. I have tried booting in safe mode and it still happens.
 
If you need more details please let me know.

Hello,
The reason for that probably is overheating.
Since there is a protection for that your computer automatically turning off instead burning.
I will recommend checking the CPU fan if the fan running as normal probably the thermal paste between the CPU and the FAN is dry and that is the reason for overheating.
Please bear in mind that can be caused by the power supply as well I`m just guessing at the moment.
Check the CPU fan and cooling system as a start if the cooling system working fine we can continue troubleshooting RAM memory and HardDrive.
Many thanks,
Andy

This sounds like a bad power supply, or some dust has lodged between some power traces on the MOBO and a standoff/support.
