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?

I do believe so, my friend!

 

[docchirodave]

One of the case fans isn't spinning or lighting up. I can't find a wire not plugged in..

 

[docchirodave]

Moved the fan to a different header. Works fine

 

[alexoiu]

Then it's ok. Good luck with the new setup!

 

[docchirodave]

Thank you! Do you have any idea about the small green led under the q code display? And its showing code a2 still, meaning ide detect. Is that ok as well?

 

[docchirodave]

Now it's doing it again. 1 long beep, 3 short beeps and no post.

 

[docchirodave]

I didn't change anything

 

[docchirodave]

I plugged in the mouse and keyboard (usb), rebooted and now the beeps and no post.

 

[docchirodave]

I unplugged then and tried to reboot. Still nothing

 

[alexoiu]

If removing keyboard and mouse, still the same?

 

[docchirodave]

Yes. I also realized I never tried to boot it with the monitor plugged into the GPU. Still had it plugged into the mb. I unplugged the GPU and rebooted with mb and it comes up. I'll send a pic of monitor

 

[docchirodave]

This is with the GPU taken out and through the mb VGA. http://imgur.com/a/UXcByrg

With such a new video card so you think the bios needs an update?

 

[alexoiu]

You can try updating the BIOS. However, what changed from the latest working configuration to " Now it's doing it again. 1 long beep, 3 short beeps and no post. " ? Just out of nowhere? You should have restarted.

 

[docchirodave]

I hadn't changed anything. I was looking at the monitor. Shut it down, plugged in the mouse and keygboard, rebooted and boom. 1 long, 3 short, and no post.

 

[docchirodave]

Again, in my foolishness this morning, when I plugged everything back in one at a time (beginning with the GPU) i forgot to move the hdmi from the vga on the motherboard to the GPU itself. There's a possibility it didn't work at any point.

 

[docchirodave]

After unplugging the GPU and rebooting again with the hdmi in the motherboard, there is that message on the monitor mentioning that the vga card isn't supported by the UEFI driver. We never saw that message at any prior point while reinstalling and rebooting devices.

 

[alexoiu]

Back to step 1.
Try powering off and removing graphics card, USB drives, any other wire than 24 and 8 pin. Start the board and see what beeps and error code.

 

[docchirodave]

I'm back at work, so I'll start back at square one tonight. Thanks again for your patience and help

 

[alexoiu]

No problem. It might take a while to answer.

The green led is not important right now,think it burns since no boot device is detected. Since not having one yet ,no OS installed on the ssd,also no usb stick to do that. So only worry about that one until you have done installing windows or even putting in a usb stick to install windows and it still shows.

You also have the latest bios so updating that is not necessary.

Maybe it doesn't make any diference but it may be good to stick to the usb 2.0 ports right now when using the keyboard and mouse.

Thank you Vic. I was wondering about the relevency of the usb 2.0 vs 3 possibly with the problem I'm having. I'll do that

 

[docchirodave]

Ok the computer posts perfect with the GPU not installed, and running the on-board graphics. Everything else is connected and running and I've installed windows 10 onto the m2 NVMe ssd. What do you advise next? Anything at all we can try before starting from square one and dissembling and rebooting as I install each device at a time again?

 

[alexoiu]

Power off and try installing the card in the second PCIe slot. See if same issue.

 

[docchirodave]

After updating windows 10 and the bios, I tried the GPU in the 1st PCIex slot again, and it worked! It's up and running.

I'm so appreciative of the help from you guys. Thank you so much!!
