Hello everyone!
I recently assembled a PC and am still trying to figure out what’s going wrong. The system starts up normally in the BIOS, with no operating system installed yet. Over time, the screen turns black (“No signal – power saving mode activated”). All components—CPU, case fans, GPU, and RGB LEDs—still function correctly. The fans on the GPU only briefly during startup before stopping, which seems fine. The issue lies solely with the screen going dark unpredictably. Occasionally, after a few minutes or even longer, the screen goes black for a moment, then everything resumes briefly before ending completely. I initially suspected a temperature problem, but according to the BIOS, the CPU and GPU temperatures are within normal ranges. The CPU and RAM were detected without issues. I attempted an OS installation once, but it also resulted in a black screen after some time. Honestly, I’d rather not risk damaging anything until I understand the cause. I’ve removed the GPU from my previous PC and reinstalled it here, and everything works properly. Do you have any insight into what might be causing this problem?

CPU: AMD Ryzen 5 9600X
MB: ASRock B650I Lightning WiFi
GPU: GIGABYTE Gaming OC 3060 Ti
When sharing a troubleshooting thread, include your complete system details. List specifications clearly as follows:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Add the PSU age along with its make and model. BIOS version for your motherboard at this time.
Is the iGPU active in BIOS?
Run DDU to uninstall all GPU drivers (Intel, AMD, Nvidia) in Safe Mode, then reinstall manually using the newest driver from Nvidia's support site via an elevated command—Right click installer > Run as Administrator.

Adjust settings, connect to the IGP...test.
Disconnect all disks, test again.
No assistance provided, at least you're aware of the basics.

Hi, here is the complete information about your system hardware. Consider trying this approach. Unplug the power cables from your graphics card and remove it gently. Attach your monitor's HDMI to the internal IGP graphics port. Restart the board using the BIOS menu. Confirm whether the display remains active with the built-in graphics; if so, proceed. Adjust the board settings to boot from the onboard graphics and install Windows with UEFI configuration. Next, install the chipset drivers for your device. Carefully power down the system, secure the graphics card firmly within the board, connect its power cables, and link the monitor. Restart the setup again and modify the graphics card selection to use the internal card via the PCIEx1 port. Test if the system boots completely without errors. This method has previously functioned for AM3 boards and recently succeeded with AM4 models.

For testing purposes, I began the PC without a dedicated GPU, only using an integrated graphics card, and it operated for half an hour without the screen going black. This suggests there might be issues with the GPU. However, I can't describe exactly what I was doing differently on my previous PC (which worked fine), except that the new build is a Mini ITX model while the old one had a MIDI case. As noted, the GPU in the older PC remains the same but has been moved to the new one.

I just reconfigured my PSU, motherboard, and GPU again, making sure all cables were properly connected. The PC now boots up even when the GPU is plugged in, but after about half an hour a random black screen appears. “No Signal” shows up, forcing me to press the reset button to restart. This happens during idle in BIOS or while booting into the OS and doing tasks. It seems the parts are unusually hot compared to what’s listed. There’s a chance I might have received a faulty motherboard, and I could still file a return request.
