Monitor displays "No Signal?"
Monitor displays "No Signal?"
I have a deal monitor configuration, and occasionally when I power it on one or both monitors, they won’t function properly. They remain on but display "no signal." Simply unplugging and reconnecting usually resolves the problem. However, recently one monitor stopped working regardless of my attempts. I’ve tried resetting the cables, using new ones, completely disconnecting the GPU, and even switching to HDMI.
During this troubleshooting, I discovered a small leak in my cooler where the hose connects to the CPU block. The fans also stopped working for what feels like an extended period. Deciding to replace it, I swapped my older H100i with a new H100i LCD model. When I first tried to boot it up, I encountered an error on the LCD screen. While attempting fixes, my monitors continued to show "no signal" issues with any cable type.
I examined the GPU and found no visible damage, though both GPUs were running with fans. I tested another GPU to see if the leak affected it, but still had no results. I checked all PCIe x16 slots, used various cables and ports—nothing worked.
I’m unable to repair my cooler because it’s completely unresponsive, and I’m unsure what might be causing the problem. I suspect it could be related to the GPU, but everything else seems functional.
PSU: EVGA Supernova 650 80 Plus Gold 650 Watt, brand new, purchased in 2019
No disk drives; I have an SSD of either 248GB or 500GB and a M.2 1TB drive.
Edit: I believe the issue was resolved—my motherboard has debug LEDs, and the system booted without problems after removing all storage devices.
Update your update with complete hardware details and operating system specifics. Provide the power supply information including make, model, wattage, age, and condition (original to build, new, used, refurbished). List the disk drive specifications such as make, model, and capacity, noting how full they are. Mention any overclocking activities.
GPU had a moment of overclocking, yet precision X tends to return to its default settings eventually. The CPU was boosted to around 4.3ghz, and the RAM should be operating at 3200mhz as well.
This item is a 4-year-old power supply unit with an 80 Plus Gold rating and 650 watts. It was purchased new and installed in 2019. A failing PSU is a probable cause, particularly given the heavy gaming usage and overclocking. Could you consider replacing it for testing? For reference: Currently there isn't an urgent need to buy a new one. Review the guide to understand PSU options and use the calculators for your setup. You might also discover other issues that could stem from a weak or failing PSU. Check the Reliability History/Monitor for any recorded error codes or warnings.
