The installation of dGPU did not produce any display output from the iGPU and dGPU.

I reviewed all connections and repositioned the RAM slots; everything is functioning properly now!
Hi,
I’m facing an issue with my older PC not displaying anything on the monitor. I’d really appreciate assistance. I assembled this system in 2017 and here are the details:
- Intel i5-7500 CPU
- Asus Prime H270M-Plus MB
- Corsair Vengeance LPX DDR4-2400 RAM
- Be Quiet! Pure Power 400W PSU
- Asus GT 1030 GPU
- Samsung EVO 960 SSD
- Windows 10 with latest updates
Previously, I used the HDMI output on the mainboard until today. Everything worked fine. Recently, I replaced the GT 1030 and installed a new one. At that time, the PC had a dGPU running for a short while without problems.
Now the issue: both the GT 1030 and the HDMI port on the mainboard fail to output anything after installing the GPU. I removed the GT 1030 because it didn’t display anything, then connected the monitor directly to the mainboard—still no output. (I was considering checking BIOS/UEFI settings for dGPU configuration.)
I cleared out unnecessary components, tried a different monitor and HDMI cable, reset the CMOS via battery/jumper, but nothing worked. I’m stuck and need guidance. The same PC-display-cable setup previously functioned perfectly; only now both displays and HDMI cables are operational with other devices. All fans are spinning, and the mainboard LEDs show power—system appears active.
Currently, only a keyboard and HDMI cable are connected; no HDD, NVMe SSD, GPU, or extra fans. What should I do next? I thought about updating the BIOS via USB and testing RAM one by one, but I suspect there’s something more obvious missing.
Thanks in advance for your help.
The power supply in question is original or built-in? Its past usage for intense gaming? What was the initial dedicated GPU? The GT1030 suggests a recommended 300-watt PSU, which should work well under normal conditions. However, heavy loads might push it beyond its limits, particularly if it's old and worn out. The source of the GT1030 could be from a mining setup where the GPU itself faces issues... In summary, your current build may need more than 400 watts overall. Check the linked review for more details. The goal is not to buy right away but to understand PSU needs better and possibly find a suitable replacement. If you can, borrow a reliable PSU with at least 500 watts from someone you know. Make sure to use compatible cables when swapping.
Thank you for your reply. The PSU is also from 2017 and has been powering this PC since the beginning. I never used this PC for gaming and always relied on the built-in GPU through HDMI, except for a short period last year when I tried an AMD RX 550. After testing, I returned to using the integrated GPU. The PSU functioned with the RX 550, which should have drawn more power than the GT 1030—hence my assumption that 400W would suffice for the GT 1030.
The GPU was purchased from a private seller who claims it was used in a standard office PC for about a year.
Thank you for the link; I believe the PSU might be the issue and I plan to test with another one. Still, I’m puzzled as to why I’m not seeing any image when I revert to the original setup this morning, such as without the GT 1030 and connected via the mainboard’s HDMI port.
UPDATE: I tested both RAM modules and now I’m getting a picture again. I’m currently updating the BIOS version and resetting all my BIOS settings. After that, I’ll connect everything else, including the GPU. I’ll report back soon.
