Intel Arc Challenger B570 OC black screen on computer start

Exod3us — Thu, 07 May 2026 17:22:28 GMT

Hi, I've been experiencing a weird problem, i have an Asrock B450m Pro4 r2.0 motherboard and an Intel Arc B570 (Challenger OC) GPU, i have a Ryzen 5 2600 it actually works fine, but when i try to use any Ryzen 5000 series, when the PC starts i have a black screen, i type Y on keyboard (cause when u change CPU it ask to type Y or N) and then i hear the windows sound but nothing on screen. I tried everything (almost i guess, if there's a solution but it might be simply a compatibility issue), disabling CMS, enable 4G, rebar, PCIe priority, force gen3 instead of auto, disable iGPU when i tried with a 5600GT, but actually i'm trying with a 5500, no iGPU and it's the same...

My question is simple, is there a solution or is it definitively a compatibility issue ? oh and of course i flashed the bios with the last version (10.60 in that case), when i use my old GPU everything good so the CPU works properly, and when i use a Ryzen 5 2600 with the Intel Arc B570 everything is fine, so the GPU works, but why with Ryzen 5000 series CPU, the Intel Arc B570 isn't recognized anymore ???

Plz if anyone can help me (sorry for my bad english)

Hi Exod3us,

Thank you for reaching out. To better diagnose the issue, I would appreciate it if you could provide the following information:

What PSU wattage and model are you using?
Have you tried disabling the SVM (Secure Virtual Machine) feature in your BIOS settings?
What is the make and model of the old GPU that works properly with your Ryzen 5000 series CPU?

Thank you for your time, and I look forward to your response.

Best Regards,

Duran J.

This is a classic "UEFI handshake" issue specifically seen when pairing Intel Arc (Alchemist or Battlemage) GPUs with Ryzen 5000 series CPUs on older AM4 motherboards. Since both components work in other configurations, the hardware is fine—the problem lies in how the BIOS handles the Resizable BAR (Re-size BAR) and Video BIOS (VBIOS) during the transition from a non-UEFI to a full UEFI environment.

Thx for your response

1. I've a Textorm 500+ it's a 500W

2. I just tried to disable SVM but it doesn't change anything

3. Actually i'm using the 5500 with a GeForce GTX 1050 Ti and it works fine

Now it's working !! I had use the 5500 with my old GPU and then change for the intel arc, i had to reboot with the new CPU first and then change the GPU, sorry it was as simple as that, i feel dumb ^^

The only issue I still have is when the windows restart, blackscreen again, i hear the sound of Windows but nothing on screen, i have to force a stop with the I/O button. On start it is fine but on restart black screen, any idea ?

Hi Exod3us,

Thank you for your patience. I have additional questions to help narrow down the issue, please let me know the following:

Since you have tried a different GPU, have you tried performing DDU?
Have you tried installing the latest driver version for your GPU?
What display cable are you currently using?
Have you tried using straight HDMI to HDMI or DP to DP?

Thank you, and I look forward to your response.

Best Regards,

Duran J.

Hi Duran J.,

1. I didn't do a DDU, i'll try that

2. I'm using the last Intel Graphics Software, it says my driver is up to date

3. I'm using and HDMI cable

4. I can't try with a DP, my screen doesn't have that

Thank you to try helping me, but i think there's lot of problems with these old motherboards, i will certainly buy a new one, do you know any motherboard that would be perfect with the Intel Arc Challenger B570 and the Ryzen 5 5500, and my SSD Kingston SNV3S1000G ?

Have a nice day Duran

Hi Exod3us,

Before you purchase a new board, I took another look at our conversation thread and noticed that you mentioned having a 500W power supply unit. According to the Intel® Arc™ B-Series Graphics – Desktop Quick Start Guide, these cards require a minimum 600W power rating to function properly. Hence, have you tried testing your system with a higher wattage PSU (if available)?

If you're able to test with a higher wattage PSU, please let me know if you notice any difference. I will await your response.

Thank you.

Hi Duran,

Thx again for your response, that's so stupid it is even written on my B570 box..., I have some word to tell to the """"technician""" i had at phone that sold me that PSU and told me "Yeah it will be perfect for your setup".... Anyway... I don't have another PSU right now but i will buy a new one soon, i will give you news in a few days, tomorrow it's a holiday in France, to be sure let's say on Monday, i'll will surely have my new PSU and i will give you news.

Have a nice day Duran

Hey, buddy!

This is actually stupid advice from an Intel employee (I think, as usual, he generated it using AI).

You can easily calculate for yourself whether your power supply is sufficient or not.

The Ryzen 5 2600 consumes an average of 65 watts (75-80 watts at maximum load)
The Ryzen 5 5500 consumes an average of 65 watts (75-88 watts at maximum load)
The Intel Arc Challenger B570 OC consumes 150-160 watts at maximum load, averaging 130 watts
An NVME SSD consumes 5-10 watts depending on the model
The motherboard consumes 20-50 watts
RAM from 2 to 5 watts
Processor cooler 1-5 watts
Let's do the math: 88 + 160 + 10 + 50 + 5 + 5 = 318 watts
You still have almost 200 watts left over
Usually, these recommended power supply labels refer to cheap power supplies that are not certified and intentionally overstate their wattage on the label. Your power supply is certified 80+ Bronze.

If your power supply isn't old, this replacement won't change anything.

Intel employs incompetent people who generate reports using AI.
And your "technician" actually turned out to be right.

By the way, you have a perfectly normal motherboard.

It's most likely a processor issue.
Both the 2600 and 5500 only support PCIe 3.0.
But starting with the 5600, PCIe 4.0 is supported.
Your motherboard is specified as PCIe 3.0, but it may silently support PCIe 4.0 in auto mode, like many Asus motherboards.
This needs to be verified.

It's more a matter of processor and graphics card compatibility.
That would be more accurate.

Hi gasoline,

Thx for your advices, but i don't really know what to do then, do you have any idea ? If you were in my situation what would you do ?

Have a nice day gasoline
