Need assistance identifying GPU problems and avoiding returns.
Need assistance identifying GPU problems and avoiding returns.
Hello,
I recently acquired a second-hand PC without a GPU. I had a GTX 950 that was functioning well before, confirming the system was operational.
To prepare for gaming, I purchased a used RTX 3060 8GB PNY Verto. Here’s my current configuration:
• CPU: Ryzen 9 5900X
• Motherboard: X570 Aorus Elite
• RAM: 32GB
• PSU: Corsair 700W Gold (original) / Corsair TX 650W Gold (tested)
• GPUs: GTX 950 and RTX 3060
The issue is as follows:
• After installing the RTX 3060, the computer failed to display properly, even though fans were running and the GPU LED lit.
• Previously, I resolved it by shutting down the PSU, holding the power button, and restarting.
• Now, when I power on the PC after a period (like overnight), the display remains absent.
• I attempted to install the GTX 950 alongside the RTX 3060 — the system booted into Windows, but the RTX 3060 wasn’t recognized in Device Manager.
• I suspected a power supply problem, so I replaced the PSU with a Corsair TX 650W Gold, connected the 24-pin to the motherboard and the 8-pin to the GPU, but the problem continued.
• Removing the CMOS battery to reset didn’t help.
I’ve tried several steps:
✔️ Re-seating the RTX 3060 multiple times and verifying all connections.
✔️ Using different PCIe power cables and another PSU.
✔️ Clearing CMOS (leaving battery out for 5–10 minutes) and resetting.
✔️ Testing the GPU in various PCIe slots.
✔️ Booting with only the RTX 3060 installed (no GTX 950).
✔️ Checking Device Manager — the RTX 3060 wasn’t detected.
✔️ Using DDU to uninstall all GPU drivers and reinstall NVIDIA drivers cleanly.
What I’m aiming to determine:
I want to eliminate any doubt that this isn’t a GPU-related fault before proceeding with a return. Since the RTX 3060 is under warranty until March 8th, I need to confirm whether the GPU itself is defective before the expiration date.
Could there be any other factors, such as motherboard PCIe slot issues or power delivery problems, that might explain this behavior?
Any suggestions or further checks would be highly appreciated!
Thank you in advance!
Hey there! What's up? Are you a friend, family member, local PC shop, or something else?
Did you verify your BIOS settings to ensure the PCIe version is configured as AUTO, which is typically the standard setting?
