New build won't boot

[docchirodave]

I just built a new system, and I cannot get it to boot to bios.

Mb: Rog Maximus XI wifi
Cpu: Intel i7 9700k
Case: Thermaltake Core X71
RAM: Corsair Vengeance LPX ddr4.
3200 16gb (2x8)
Ssd: Samsung 960 Evo NVMe M2 500gb
Gpu: Evga Geforce RTX 2080 XC
Hdd: Seagate Barracuda 4tb 6ghz 256mb cache
CPU cooler: Evga CLC 280 liquid/water cooler
PS: Evga Supernova 850w P2 fully modular 80+ Platinum
Windows Home OEM

I meticulously put everything together, crossed my fingers, and hit the power button and....no post. It won't boot to the monitor.

The motherboard does one long beep, 3 short beeps and displays the q code A2. It also has the small white and green led's lit next to the q code display.

I have reseated the m2 ssd, moved the ssd to the other m2 port, tried to boot with only the hdd and no ssd, switched SATA cables on hdd, reseated GPU, moved GPU to another PCIe slot, snuggled up all connections on motherboard, and reseated and flip flopped the RAM modules. Same codes and no boot every time.

Please help, gurus! Hopefully I dont have a bad motherboard. Has anyone else run into a similiar problem?

Have you tested with graphics card removed?

 

[docchirodave]

Thank you for replying. Yes, I did try to boot up without the video card. Same thing, no boot and same beeps, leds, and A2 code.

You're welcome.
What video cable using to connect the monitor? DVI, HDMI?

A2 would be ok, but the beeps indicate a video error, which is not ok. Have you messed with Flashback?

 

[docchirodave]

No, I haven't ever tried that. It's flashing the bios, right? I'm not sure how to go about it

 

[alexoiu]

Then not sure about the issue. Try removing the CPU, taking a picture of the CPU socket, uploading it on imgur and posting the link here, to check for bent pins.

Maybe also post pictures of the motherboard inside the case so people can look how all is connected.

Otehr thing,you might want to try and see if updating the bios might help. There's a "first release" bios and a secondary "Version 0602 from 2018/10/31" which states "" Updated Microcode for 8-core CPU".

Using USB BIOS Flashback, please rename to "M11HW.CAP" after download! Unpack the file before renaming it and putting it in the usb stick.

 

[docchirodave]

I'm at work right now so I can't post any pics yet. I downloaded the bios update to a USB stick so I can try that at lunch.

Thank you guy so much for your help. I really appreciate it

 

[alexoiu]

I suggest not using Flashback until solving the no post issue. It might add to the problem, if not successful, instead of solving it.

 

[docchirodave]

Alright, I'll take that advice. I pulled the CPU yesterday and looked carefully at the motherboard and CPU itself. I don't see any bent pins or abnormalities. What do you suggest I do next?

 

[alexoiu]

Can you post a picture of the socket?

 

[docchirodave]

At lunch today I'll take some pictures and post them.

Here's the CPU, the socket, and a few pics of the build. Not the best lighting, so if you can't see it well let me know and I'll try and get some better photos.

 

[alexoiu]

The link is for single picture.

[docchirodave]

Try that

 

[alexoiu]

Pins look ok. What code and beeps getting if starting the board with only CPU and CPU cooler installed, both 24 and 8 pin power cables connected (no other components, or wires connected)?

 

[docchirodave]

I'll have to run that after work tonite. I'll do it ASAP when I get home. Just to clarify, take out the M2 NVMe ssd and the RAM modules as well?

 

[alexoiu]

Yes. Leave only CPU, CPU cooler and power cables.

 

[docchirodave]

Alexoiu, I see where you're headed and I like your thinking. Try to boot with no peripherals, and if we get a code it almost has to be the mb or CPU. Then start plugging peripherals back and and booting until we find the culprit.

 

[alexoiu]

Yes. Start from basic.

 

[docchirodave]

By the way, alexoiu, it's people like yourself and vic40 up there that make the internet a great thing. Communities like this helping other people. I'm very appreciative.

 

[alexoiu]

Thank you very much.
