Dell Vostro 3400 shuts down after a minute...

[MyAntsRMarching]

Hello all,
I have a Dell Vostro 3400 that just had its motherboard and ram replaced by Dell. It is not out of warranty. It was built in 2011. It was working fine at the office after the replacement, I took it home, it installed some updates, then after a minute it shuts off. I have tried a new hard drive, diagnostics, save mode, bios menu, no matter where it is, after a minute give or take it shuts off. Any ideas?

I made a video of what it does. Any ideas?

sounds like the CPU is over heating. try changing the thermal paste. try updating the bios. also because its a different mobo, you may need to reinstall windows.
