Computer starts starts then shutsoff

[Jason Bowers]

So about three months ago I got my computer built and everything was running just fine, until recently. I was just watching Twitch when all of a sudden my computer shut off. I tried turning it back on to it starting then shutting right off, not posting at all. I brought it to a local computer shop and they didn't have the right diagnostic tools to test my pc, but they told me my motherboard most likely is the issue. So I sent it back to Asus and I just got my motherboard back from them to get the same issue. I did some looking around and I decided to take my cpu out to find out that it booted up further than it has and stayed on.

Now I am at a pickle and I don't know if Asus sent me another faulty motherboard if it is my cpu that is the issue.

Has anyone else ran into this situation and have any idea on what could possibly be causing this?

a hard shutdown almost always is a temp issue. is the cpu cooler / fan working?

well it could be a dead psu or cpu too.

Yes, everything powers up fine. I actually bought a new PSU thinking it was that and it did the exact same thing,

its just flat out shutting down prior to post without an error message?

you are 100% sure that h100 has a pump thats running? can you feel the tubes to see if they're hot? Cause I'm pretty sure you should get some sort of bios message with almost any problem except a dead PSU/CPU or overheating problem.

those 140W intel chips can melt down in less then a second if they're not getting proper cooling, and it's not unheard of for the pump to break in some way or the liquid to dry up in one of those AIO coolers.
