VGA LED activated showing GPU issue, yet GPU functions properly in another system
Hi everyone,
I have been pulling my hair out trying to find the problem in my new system build.
In my current configuration my system won't boot and the white VGA LED on my motherboard stays lit, indicating a GPU problem.
First, my full part list:
CPU: Intel i5-13600KF
MB: Asus ROG STRIX B760-I
GPU: Sapphire Radeon RX 7600
RAM: G.Skill DIMM 32 GB DDR5-6000 (2x 16 GB), F5-6000J3636F16GX2-TZ5RK
PSU: Cooler Master V650 SFX Gold
SSD: Kingston FURY Renegade (2000 GB, M.2 2280)
CPU Fan: Scythe Big Shuriken 3
Case: Lian Li Q58
Here is what is happening when I power on the PC:
Red LED turns on and goes off again, indicating CPU is OK.
Orange LED turns on and goes off again, indicating RAM is OK.
White LED turns on and stays on, indicating GPU is NOT OK.
Green LED turns on, indicating boot sequence is starting.
The monitor stays black.
I have tried connecting the monitor to the onboard HDMI port, using a Display cable, changing the monitor, and removing the GPU to force the system to take the onboard graphics. I have updated the BIOS to the latest version. I have tried one or both memory sticks. The monitor always stays black.
I have then put the GPU into my old system and it boots fine. I can boot into Windows, install the GPU driver, and the system runs just fine.
I then took my old GPU (ASUS GTX 660 Ti DirectCU II) and placed it into my new system above. Then the following happens:
System starts and clears LEDs as above. When reaching the white LED, system briefly turns off and turns on automatically again.
System clears the white LED, the monitor display works, and I can enter the BIOS.
I feel like I have eliminated all possibilities of an individual hardware problem. According to various website, the different parts should be compatible with each other.
Do you have any tips on how to troubleshoot this some more? I have exhausted all the options I can think off.
Thank you for any help!
That is a good point. So trying to have it switch to igpu is pointless.
Do you have any tips on how to narrow down the issue? As using another gpu on the same board works, I don't understand what the problem could be.
A quick update: your suggestion that the MB might be the problem led me to taking everything out and trying minimal configuration on the board. This included putting the gpu directly into the board instead of connecting it via the riser cable.
In this setup it works. But as the other gpu worked with the riser, I don't think it is faulty.
I will keep experimenting.
The cable provided is part of the lian li q58 package.
From the site, only "PCIe 3.0 or PCIe 4.0 riser cable for vertically mounted GPU" was listed.
Thank you for the kind words. I'll try it out and let you know the outcome.
