The computer starts up, yet the display fails to show any HDMI connection.
Last night I watched anime and played Valorant. This morning my PC turned on but the monitor displayed 'No HDMI signal.' After turning off the PSU briefly and then restarting, it booted up to Windows. This has happened a couple of times now. I bought the PC just two months ago—what might be wrong? Help needed!
It seems your computer is having trouble starting sometimes. This might occur if power is lost during shutdown or restart, or if the shutdown process isn't done correctly. You should also verify that your CMOS battery is functioning properly.
Batteries have varying lifespans. You rarely get details about how long a battery stayed in packaging, how long the motherboard rested on the shelf before assembly, or how long the finished unit was stored before purchase. Typically they last 5 to 8 years, though this isn't guaranteed for every unit. Sometimes faulty power supplies or failing capacitors can cause such problems, which is why many manufacturers opt for Japanese capacitors at 105°C. Also, consider whether you're using a riser cable or a vertical mount kit for your GPU. A recent discussion highlighted an issue linked to a defective riser cable.
