New Case and computer stopped working

[black.jacket1545]

I got a new case for my prebuilt computer which was a Hp Envy Phoenix 860-160se and I didn’t like how small the case was. So I decided to get a new case which was a Kopplen Z3 ATX case and I have a mATX mother board which is the Hp Viking X99 (it came with the prebuilt) The old case worked perfectly I just wanted more space but when I plugged everything in it powered on and the fans start for 1 second then stop in loop. Only the power button led lights up for a second then turns off when the fans stop. I was having a lot of problems finding which switch belongs where because the prebuilt MOBO had no manual or any indications of what went where. I the Power Button and the USB 1/USB2 and the audio seemed to all be plugged in fine. The plugs are in perfectly fine and the GPU PSU CPU and RAM are all working. I don’t know if mounting the motherboard could be the problem. But I’m very new to this so I am not sure

In the new case, is there a spacers for the motherboard ? Check to see if the mobo is touching any metal.
I had a same problem week ago and was from one of the RAM sticks. Take them out and put them in again.

There are spacers but I didn’t touch them at all and the mobo isn’t touching any metal. I just used some screws that came with the case to screw it in. I’m not sure what to do with the spacers

Check the mobo connectors. Are they put in the same way as before.

When you say "spacers" do you mean standoffs? There should be a standoff under each screw holding down the motherboard into the case.

I have standoff’s that hold the MOBO down and I have spacers which came with the case in a little packet along with a lot of screws

Yes, ok i meant standoffs.
Did you remove the CPU cooler while changing the case ?

I didn’t remove the CPU cooler it’s liquid cooled

Your original post is confusing to me. In the first part you say the computer will "start for 1 second then stop", but in the second part you say "the GPU PSU CPU and RAM are all working". How do you know these parts are all working properly?

Because they were all working about 3 hours ago. And I handled them very gently making sure they were not getting damagaged. But maybe you are right. Is there anyway to check?

You can remove the cooler even if it is liquid.
rocktalkrock is right - how do you know the parts are working properly ?

If I do will I need to reapply some thermal paste?

 

[Multyspeed]

sorry for the post above.
How many RAM stick you have ?
Yes - new paste for the cpu.

 

[black.jacket1545]

2x8 GB

remove one stick and try turn the pc on.
One stick at a time.

 

[rocktalkrock]

To be clear i don't suspect the parts were physically damaged, just jarred out of place when you took out the motherboard. The motherboard will flex a certain amount when it's not held down flat by the screws.

 

[Multyspeed]

I agree with rocktalkrock. I had the same problem a week ago. I change my case and the had the same problem. Reinstall my ram sticks and now everything is working fine.
Sorry for my bad english - it is not my mother language.

Have you tried to reset the bios ? Check if everything is plug in as it should be.

How do I reset the bios? And everything is plugged in right

Unplug the computer and remove the motherboards coin battery for 30 seconds. That will change the BIOS to default settings.

It ended up being my motherboard and I replaced it today and everything worked! Thanks for trying to help
