blinking power button
About this tag
The blinking power button on a Windows desktop PC often indicates a hardware or power issue. In one reported case, a machine shut off suddenly and the power button began blinking slowly, failing to respond to presses. This occurred after a power supply replacement, suggesting possible PSU incompatibility, improper installation, or a motherboard fault. Troubleshooting steps may include checking power connections, testing with a different PSU, or inspecting for short circuits. The blinking pattern can vary by manufacturer, so consulting the motherboard or PC manual is recommended for specific diagnostic codes.
