Signal no longer coming in unexpectedly
Signal no longer coming in unexpectedly
My GPU appears to be the problem area. I tested it with an older unit and it functioned properly. After a few hours on my new PC, both the monitor and keyboard stopped getting signals (monitor signal and keyboard power). Rebooting fixed the issue, so I didn’t worry much. I was playing FFXIV at the time. However, a few hours later the monitor lost the signal again, and I haven’t managed to resolve it yet. This happened after launching a benchmark for the new FFXIV expansion—maybe it’s connected. This is my first build. Fans spin up correctly on boot (CPU and GPU), keyboard is powered, everything seems normal except the "No signal" message on the monitor. I checked the pinned topics, tried most fixes. There were some cable connection issues during setup and at first boot, but now I’m pretty sure the monitor is properly connected to the GPU via HDMI.
Specs: Windows 11, Gigabyte B550M DS3H AC, AMD Ryzen 5 5600, Silicon Power XPOWER Turbine RGB, 32 GB DDR4-3200 CL16, XFX Speedster SWFT210, RX 7600XT, Western Digital Black SN770 2 TB M.2-2280 PCIe 4.0 X4 NVMe SSD.
System: Power 9 700 CM, 700 W, 80+ Bronze certified, semi-modular ATX power supply, Acer Nitro vg271um3bmiipx.
The cable appears to function properly. It’s currently being used to link the monitor to my laptop. I switched its orientation and the port it connects to, and everything operated correctly. (I’m attempting to test with a different cable too) EDIT: No, I tried another HDMI cable but it still doesn’t work.
Updated: Swapped my GPU for a previous model (AMD Sapphire Radeon HD 7870). It’s functioning now. Still unsure—could it be driver problems, or is it completely faulty? Need advice on next steps.
