PC stops working and turns off again during gameplay.
Hello everyone, thank you for your time and assistance.
About a year ago I replaced my old GRX 960 with an RTX 3060 and everything functioned perfectly. But lately, over the past month, my PC has been shutting down repeatedly whenever I play games or engage in more intensive tasks like fighting. Additionally, this week I encountered an unusual issue: both my screens went dark while the computer kept running, requiring a manual restart, which resolved the screen problem and hasn’t occurred again.
Initially, I managed to prevent these restarts by capping the maximum FPS of the games, but recently it seems to be worsening (even at very low FPS) and I can no longer play comfortably.
Here are my observations so far:
1. Temperatures remain ideal for both GPU and CPU.
2. My first concern was the power supply unit (PSU); with a 7-year-old 750W unit, I checked its output voltages using a multimeter, and everything was within normal ranges.
3. Restarts occur even when the GPU is only drawing 70W (thanks to the FPS limit), suggesting the PSU might not be the issue. I attempted to restart the old 960, but restarts stopped even at its maximum consumption (around 170W).
4. The RTX 3060 performs well, but it triggers a restart when something goes wrong on the screen. This leads me to suspect a problem with the PSU’s ability to detect GPU power spikes and potentially shut down the system for safety.
Do you think this situation is similar to what I described in post 4? I’ve read that power spikes are common in the 30 series, and my 7-year-old PSU might not be handling them well.
On the other hand, does it sound like a GPU-related issue to you?
This issue is really frustrating. Any feedback or advice would be greatly appreciated. Thank you.
Use a flashlight to inspect your power supply thoroughly. Check how dust has accumulated. Have you ever tried blowing it out? Over time, as the days grow longer and dusk approaches, upgrading now can prevent future headaches. Also, while temperatures are fine, it’s wise to shine a light on the GPU using the flashlight as well. Point it at the GPU fan and examine the card near the end where the grill connects for HDMI and D/P. Then shift your gaze down to the GPU heatsink. If you see light shining through all the fins, everything looks good.
