Need advice, new Rig alright for 30mins, then won't post.

[Apharex]

Just spent 3-4hrs trying to troubleshoot, without success. You guys are my final hope.

Today after a long time thinking about it, I made a new rig.

ASUS Z790 Dark hero
Intel i9-14900KF
Nvda RTX 4080 S
DDR5 6000 32gb x 2
Windows 11 

I was very happy to see it boot up just fine on first try.
Started to download my usual games on steam, and was kinda excited.

Started playing Helldivers, and GPU was giving very good FPS.
Then 10mins in, Display froze.  PC crashed.

At first I was like "oh, ok, new rig, probably need to tune it a bit"
but then, waited and waited, PC won't boot.   Reset, won't boot.  Power Off completely.... still cannot reboot.
I notice Motherboard has error Code 00, and machine won't even post.


Is my motherboard fried?  
20mins right out of the box from brand new?
Or is my CPU faulty from some extreme bad luck?

But the machine was Working really well for 20mins.
then suddenly fails.

I know I will be throwing more savings to fix the problem.
but can anyway help me keep the cost of repair low?  What you think is most likely the problem?

I am heartbroken this moment, appreciate help.

Code 00 related to cpu problem. Reseat the cpu and set the bios default. If it still no post take it to shop to test. Don't think the cpu just die like how you mentioned.

Hi @Apharex 

Not the best start to a new build, sorry to hear that.

1. Remove the CPU cooler and CPU and inspect the CPU pin-pad and socket for any debris or damage.
2. If using a CPU contact frame, remove the frame and reinstall the stock retention bracket.
3. Clear CMOS, remove CMOS battery and AC for 3 to 5 minutes and retest.

Tried reseating CPU, also tried a different cooler (from older computer)

Still won't post. starting to feel I need to renounce my faith. 

There's no visual abnormalities on the CPU pin or seat of the board.

Running out of ideas.

shop is very far from where I live.

I think I will just have to get another CPU, get another board.

Rinse and repeat.  anyone with other possible leads or things I might have missed?

[Silent_Scone]

If possible, I would consider taking it to a system integrator or returning both parts to the vendor. Depending on the point of failure, plugging a dead CPU into a working board or vice versa is not advisable.

[Apharex]

Just following up.... I am starting to suspect, my chassis might have a part to play in this.
This chassis is something I am re-using, and the previous built, also had a 'mysterious' Unbootable death.  (though that I thought related to the RAM)  but 2 events in 1 chassis... which means I cannot run that out completely.

I am not sure what is failing, M/B or CPU with the 00 code...
Just have to tackle the issue one by one I guess....  this will be costly....

[Silent_Scone]

Do you suspect the chassis might be shorting the motherboard?

Are you reusing the same PSU, too? More reasons to perhaps get a sys integrator to test the components.

[Apharex]

The PSU is new.  But yes I am suspecting the chassis might be shorting the board.

especially with higher voltage these days, maybe this chassis just wasn't made for this generation..

Long story short:  I got a new chassis.  I returned the mother board and CPU for a newer version.  (they charged me a bit)
But now the whole thing boots fine,  will be doing some stress test later today to be sure.

[Silent_Scone]

There’s no correlation to be made between any voltage and the chassis. If the chassis is to blame, it will be due to a short or improper mounting. 

Anyway, glad you were able to resolve. Keep us posted 👍

Had a few years of experience building my own and family rigs. Some recommendation when you are assembling PCs.

Use Washers - I usually place those non-conductive fiber washers between the motherboard and standoffs on the casing. Just to prevent potential shorts.

Quality Power Supply (PSU) - Never ever scrimp on quality power supply unit. A poor quality PSU will potentially destroy all the components.

Install Power Surge Protector - If possible, install a power surge protector between the power point and your PSU. Especially so if you have high power equipment such as refrigerators pulling power from the same circuit.   

Good Luck.
