Computer shuts down after a few seconds

My computer was working fine, and then I did a windows update. After my PC restarted, it was on the login screen for about 10 minutes and then shut down.

I have been researching this issue for days. I have taken out the motherboard battery, removed all components and installed them again one by one to make sure all wires are connected.

It seems that the system loads up and the hard drives begin to spin and then it shuts down. I realized this because I did not have the hard drives plugged in initially and it shut off relatively quick. I hooked up the hard drives and it doesn't shut off until a few seconds in. I am assuming that the startup BIOS runs through the components. I can't seem to figure out what's wrong after the hard drives though, any suggestions? The mobo and PSU seem fine and I've tested them, and it's powering on for a few seconds so I don't believe it would be the CPU. I also took apart the power button and made sure no gunk or anything for it to stick.

Hopefully you guys can help, thanks in advance!

I finally got it working, was good for about 30 minutes. The computer went into sleep mode, when I tried to boot it back up I was back at square one. Lights up for about half a second and fans begin to spin. I am thinking this might just be the PSU or MOBO failure. Any suggestions?

Turned out to be a faulty PSU. I gutted everything, bought a new psu, and rewired everything. Worked. Also note that a few weeks before my PSU went out, my computer would only start up if I unplugged the power cord and plugged it back in. Might be a sign.
