Hi everyone,
I’m having a strange issue with my PC and I’m trying to figure out if my GPU is dying.
Specs:
Ryzen 5 5600X
RTX 3060 Zotac Twin Edge 12GB
Gigabyte B550M DS3H
DeepCool PK650D PSU
Lexar 16gb ddr4 3200 MHz single stick
Issue:
The PC will often boot normally if it has been completely powered off for 2–3+ hours. It’ll reach Windows, and everything seems fine. However, after about 15–20 seconds, the screen suddenly goes black.
After I force shut down and try to restart:
No display output
Keyboard and mouse don’t power on
All fans spin normally, including GPU fans
Sometimes after leaving the PC off for several hours, it will boot again and repeat the same behavior.
Things I’ve tried:
Updated motherboard BIOS
Reseated the GPU
Checked/reconnected GPU power cables
Tried multiple restarts
Ran FurMark when the GPU was working (around 80°C core, 91°C hotspot, no artifacts or crashes)
Once the PC boots successfully, I can sometimes game normally without any noticeable issues
Has anyone experienced something similar? Does this sound like a failing GPU, VRAM issue, power delivery problem, or something else?
