Question Can not get PC build to boot ?

[angelh55]

Hi. I built 2 identical PC's and neither wants to boot.

Specs:

Corsair iCUE 4000X RGB Case

Corsair RM 850X power supply

Asus Z590-A Motherboard

Intel i5 10600K 10th Gen Comet Lake 6-Core 4.1Ghz LGA 1200 125W

Samsung 970 evo 1TB nvme

G.Skill Ripjaws 32x1GB RAM DDR4-3200 Intel XMP 2.0 Ready

EVGA GeForce GTX 1070 FTW GAMING ACX 3.0 8GB GDDR5, RGB LED, 10CM FAN, 10 Power Phases, Double BIOS, DX12 OSD Support (PXOC) Graphics Card 08G-P4-627

NZXT Kraken X53 Cooling

TP-Link WiFi 6 AX 3000PCIe WiFi Card (Archer TX3000E) up to 2400mbps, Bluetooth 5.0, 80211.AX Dual Band Wireless Adapter

This is my 5th & 6th build. Never ran into a problem before. I notice this motherboard has an additional 4 pin power connector to the left of the standard 8 pin power connector near the top left of the motherboard. When I plug in the power cord to the power supply, the RGB lights do light up on the motherboard only. So I know it's getting power. But that's where it ends. It will not boot at all.

I put the 1 stick of RAM into the DIMM A2 slot as recommended on motherboard manual.

On the 2nd PC built it exactly the same minus the EVGA graphics card. So I can reach and press the power button next to the 6 SATA ports. Motherboard gets RGB lighting but still will not boot up. I checked all case wiring requirements, USB to motherboard connectors including the ones for the KRAKEN X53 cables for water cooling.



I double checked the power consumption requirements:

Motherboard (254 watts)

CPU (125W)

NvME (6W)

RAM (11.85W)

EVGA GPU (315W)

KRAKEN X53 (3.84W)


Total wattage used = 715.69 Watts from a 850 Watt power supply.

I am at a loss here. Please help me figure out what is wrong. What did I miss? Thanks in advance.

May be an hardware issue.

Nope. I have a theory. It's acting like it does not recognize my CPU. Possibly current BIOS firmware is not familiar with the following CPU until after a firmware update.

Intel i5 10600K 10th Gen Comet Lake 6-Core 4.1Ghz LGA 1200 125W

I suspect I need to initiate a BIOS flash so that it WILL accept and recognize the new CPU. I'm going to call ASUS to confirm. I suspect I'll need to purchase an acceptable CPU like a

Core i3-10100F (3.6GHz, 65W, L3:6M, 4C rev.G-1) for $100

to be able update the firmware. I wish this was like an MSI motherboard where you can flash the BIOS without a CPU needed. I will find out later on today.

No cpu is supported from first bios.

Sure you connected all cables right? Even or maybe especially frontpanel?

Did speak with ASUS support. Turns out the i5 CPU specs are included the BIOS based on serial number information. So the CPU is not the issue. Will call ASUS when I have the PC in front of me for further tech support.
