[SOLVED] So I'm screwed then? New Build, flashing light then immediately off

[ForestDingo]

I took everything out of the case after the same issue with the flashing for a second then going out. So now I only have the CPU in with the heatsink. It's an Z390 Aorus motherboard -

I assume the motherboard is dead?

You need memory installed for the system to post.

 

[ForestDingo]

Same thing with RAM in it as well, tried different slots and everything

What model CPU do you have installed? Do you know what BIOS version is installed on the motherboard?

It's an I9-9900k - https://www.newegg.com/core-i9-9th-gen-intel-core-i9-9900k/p/N82E16819117957?Item=N82E16819117957

Not sure about the Bios

What specific motherboard (full model as there are several variants)?

Depending on the stepping of your CPU, you may need a different version of the BIOS installed. See here:

https://www.gigabyte.com/us/Motherboard/Z390-AORUS-ULTRA-rev-10/support#support-cpu

For a particular stepping, you need the indicated version number, or newer, installed before using that particular CPU.

Oh, so I'm a beginner, how would I setup the bios when I can't get it to work/turn on?

 

[COLGeek]

You should be able to determine the stepping number from reading the information stenciled on the top surface of the CPU itself. That means removing the heatsink and cleaning off the thermal compound.

To install a BIOS update, you need a compatible CPU installed first.

Lets figure out what you are working with.

Wouldn't this info be the match across all the same CPU models? I really don't want to remove the heatsink again and reapply the paste, super OCD and all that. I will if you think that that's really the problem,

I'm just worried I might have shorted something out as I didn't wear a grounding strap when making it and was on carpet.

Is that board's supplemental power CPU ATX12V connected from PSU? (likely an 8 pin)

There's a 4 pin, and then an 8 pin right next to each other. I'm using the cords listed as CPU that are 2 4 pins into the mother board, that goes into an 8 pin into the Power supply.

Look at the compatibility link sent earlier. There are two different steppings indicated for your CPU. They require different BIOS versions to work.

Alright, It'll take me a minute, but I'll get the heatsink off.

Thank you

 

[ForestDingo]

Ok, doing it now. As for the heatsink, it's a Noctua NH-D15 and I do screw it down as far as it can go. This ok to do?

Yes. You tightened all the way.

So here's what I have. I'm thinking of taking the CPU out and having a look at the pins, I did apply pressure to it while cleaning it with alcohol and there was alot of resistance while closing the latch that secures it in place. I'm positive I lined up the little corner arrow correctly though.

Where did you purchase that CPU from?

Newegg, should I take it out and have a look?

 

[COLGeek]

Nope. Not necessary. Just wondered.

Looks like the R0 stepping. Needs motherboard BIOS version F7, or newer, to work.

CPU info can be found here:

http://www.cpu-world.com/sspec/SR/SRG19.html

Were there any labels on the motherboard box that might indicate its installed BIOS version?

Hm, not that I see.

If you want I can take more pics though

 

[ForestDingo]

I took some extra pictures, of the CPU socket and the Chip. Also on the motherboard I did some red lines. Is this where the 2 x 4 CPU cord goes to power the mother board?

The hardware seems okay. Since you have a R0 stepping CPU, your motherboard MUST have the proper BIOS version for it to work. From the earlier info that was provided, that means F7 (or newer).

Do you have access to another compatible CPU (see previous link for what will work) that could be used for troubleshooting and updating the BIOS?

I don't know to be honest, the last PC I built was 5 years+ ago. But I still have the order history of it - https://www.newegg.com/intel-core-i7-4th-gen-core-i7-4790k/p/N82E16819117369?Item=N82E16819117369
