I am building a computer with these parts:

MBD: Gigabyte B550 AORUS ELITE V2
CPU: AMD Ryzen 7 5700X3D
RAM: Corsair DDR4 Vengeance LPX 2x16GB 3200 CMK32GX4M2E3200C16
PSU: Corsair RM650
Water Cooler: Corsair H55 RGB
Case: Lian Li Lancool 205 MESH C White
GPU: Gigabyte Radeon RX 7600 GAMING OC 8G
SSD: Kingston KC600 256GB 2.5"
HDD: Seagate Barracuda 3.5" 2TB ST2000DM008
Intel Wi-Fi 6E AX210 Internal WLAN / Bluetooth
Arctic MX-4 heat sink compound Thermal paste 4 g
OS: Microsoft Windows 11 Home NL OEM

The problem is that when I turn on the computer, the fans start spinning (yay) but also that the motherboard lights up completely orange and that nothing appears on the screen. So I can't get to the BIOS.

According to the internet, possible causes that I have already checked are:
- incorrectly installed CPU (no idea how you can do that because you can only get it in the socket in 1 way)
- loose memory banks (I have already taken them out and put them back in several times, they are also in the correct slots)
- CMOS that needs to be cleared (I did)
All those tips come from here: https://forums.tomshardware.com/thr...rd-show-orange-light-and-blackscreen.3790882/

Furthermore, I have also tried with as many parts removed as possible: without graphics card, without SSD, without HDD, without most connectors of the front panel of the case (everything except the on/off button). That makes no difference.

Does anyone have an idea what else I can try? I just hope I don't have to return the whole thing because, for example, the motherboard simply doesn't work.

Another unimportant side question: for the 'Intel Wi-Fi 6E AX210 Intern WLAN / Bluetooth' there appears to be no slot at all on the motherboard. It seems to me that the card needs an M2 Key E slot, and the motherboard only has PCIe. Or am I seeing that wrong?

This:

"The problem is that when I turn on the computer, the fans start spinning (yay) but also that the motherboard lights up completely orange and that nothing appears on the screen. So I can't get to the BIOS."

Details needed.

Are you able to take some photographs showing "completely orange" and post the photographs here via imgur (www.imgur.com)?

Do you have the motherboard's User Guide/Manual?

what revision is your board? there is rev1.0/1.1 upto 1.5 1 of those have the "wifi built in".

i would suggest you find the revision number then go to gigabyte site. and download latest bios drivers for your revision. . and take out "cpu, ram, ssd/nvme.. and just plug in 24 pin power and 8pin power
then insert usb stick with latest bios and turn on power then press "q flash button on back on motherboard and it will flash to latest bios ,.. once finished (about 10 minutes max) you can unplug from psu. and install all parts again and then power on and you should get a working pc. . (do not clear cmos until you have booted into windows successfully, of it could corrupt bios.
......
important note.. for when bios flashing..

make sure usb stick is less than 32gb...
formatted to "fat32"
bios folder is unzipped and re named "gigabyte.bin". (check file extension is on in folder).
watch the red flashing led by "q flash button" if will flash red slowly for a few seconds and then faster. this means its working.. if it stops after a few flashes, it means you did something wrong. and need to try again.


i hope this helps

Thank you for your help.

Here are the pictures:

(let me know if you can't access those picture. I've never used imgur before)

As you can (almost) see on those pictures: the motherboard has
- the 2 power cables (8 pin and 24 pin) attached
- 2 memory modules inserted
- CPU inserted
- cable to on/off button inserted (bottom of picture)
- cable to 'system fans' inserted (makes the fans of the case spin)(bottom of picture)
- 2 cables to the 2 fans of the watercooler inserted (top of picture)
Nothing else is connected

More details about the steps to get to the issue:
- I turn on the power on the power supply
- I push the on/off button on the case
- Immediately, all fans start spinning. No lights at all on the motherboard.
- Two seconds later, the orange lights on the motherboard turn on
- Nothing ever appears on screen, so the computer doesn't seem to reach the BIOS.

I do have the motherboards manual (https://download.gigabyte.com/FileL...1503_e.pdf?v=dfe93ebb99075c5b2fec6247ebaf1008) but that hasn't helped me too much. There's no mention of the 'orange light' in the manual.

Thank you for your help.

The motherboard is REV 1.5. You're right, it include WIFI: Gigabyte B550 AORUS ELITE V2

I'll try the BIOS upgrade and will let you know what happens.

Is it possible that the memory modules are incompatible with the motherboard?

I'm trying to use Corsair DDR4 Vengeance LPX 2x16GB 3200 CMK32GX4M2E3200C16 Memory module but that doesn't appear in the list of compatible memory: https://download.gigabyte.com/FileL...ermeer.pdf?v=390bb5e1cba06dbd4601a1444a6ddffd

In fact , there are 13 types of memory in the list starting with CMK32GX4M2 , but all of them have as the next letter A, B, D or Z. None of them have E as the next letter (like the memory sticks I'm using).

Could that be the issue?

Answering to myself: that's probably not the issue.
I see here https://forums.tomshardware.com/threads/difference-between-these-2-corsair-ram-models.3717688/ that those lists only contain the types of memory that were tested with the motherboard, but any memory module that fits should work.

The orange lights on the board are part of the RGB so this is just the standard colour of the board. If you look at any of the marketing photos of the board this is how the board looks when powered on.

I am sure this is not the case but you are plugging any display cables into the GPU directly and not into the motherboard? The 5000 series do not have an igpu and so cannot output a display. I saw you mention trying it without the gpu earlier so worth checking.

I take it you have tried with just 1 stick of memory and have checked the socket to make sure no pins are bent or any debris?

The tubes on the AIO do also look quite tightly bent and this can sometimes cause pressure on the socket which in turn can cause some issues and prevent a POST.

If all these have been checked then my next step would be a BIOS upgrade as mentioned using the Qflash option as others have already mentioned.

I have several boards with orange "strip lights" that often define the PCB area around the audio codec chip and "audio grade" electrolytic capacitors. It's a modern take on the green LED found on much older boards to show that power is applied. If you see an orange strip light or an illuminated green LED, it's supposed to stop you from plugging in or removing components, without switching off the power completely. Sometimes the strip light comes on when +5VSB is present and no other rails are present.

I've used Corsair Vengeance in a number of boards and not had any trouble booting at the default JEDEC speed(s). For DDR4 that's probably 2133MT/s or 2400MT/s. The only times I've had problems is when trying to run significantly faster XMP speeds, well above the JEDEC default, but that's perfectly normal behaviour When you power on a new build, the BIOS normally pulls the JEDEC default speed and timings out of the SPD chip on the DIMMs.

As @MEMOFLEX says, make sure you've got a known good (tested in another PC) graphics card plugged in and connected to your monitor.

First thing, check the CR2032 battery. I have had numerous old boards fail POST when the battery is flat (low voltage), or not connected properly. I know this is brand new board, so the CR2032 should be healthy and around 3.25V DC, but if the battery is not plugged in properly (bad contacts) the BIOS might not be receiving any voltage and as a consequence, refusing to POST.

If you have a multimeter, connect the negative lead to chassis and touch the top of the CR2032 with the positive probe. You should see around 3.25V. Anything less than 2.8V and I change the battery, but it's worth removing the battery and testing again, to see if the voltage measured changes.

The next thing I'd do is to (VERY CAREFULLY) remove the CPU and look for bent contacts in the socket. It is critical that you do not drop the CPU into the socket, when fitting or removing. The contacts are horribly delicate and one bent contact can result in failure to boot. If you do have bent contacts, you might be able to straighten them without snapping them off.

Similarly, people on this forum admit they've clumsily contaminated the CPU socket contacts with blobs of thermal compound. When they try to clean up the mess, they bend the contacts. When they try to straighten the contacts, they snap off. Game over. Buy a new motherboard.

You CPU might not be seated properly and the (simple) act of removing and refitting it may cure the fault. Take care.

Do you have the AIO pump and the radiator fans plugged into the correct headers on the mobo? If the BIOS cannot detect the presence of a cooling device (tacho output), it may refuse to start, to prevent the CPU from "overheating". Check the motherboard manual and see if there is a preferred position for the pump (CPU_PUMP) and the radiator fans (CPU_FAN). If swapping AIO cables around doesn't work, try a simple air cooler if you have one.

I've resurrected some systems by powering on with no DIMMs fitted and waiting a minute or two, before powering off and fitting one DIMM. If it POSTs, I switch off and fit the remaining DIMMs. You appear to be using the "correct"DIMM sockets A2/B2 in your photo.
