I've experienced this No DP signal not found issue repeatedly. The screen stays black with no signal, appearing every 15 minutes to a few hours. I've tried all the troubleshooting steps so far without success. My PC (all new parts) runs with a CPU from Reyzen 5 5600, a Gigabyte AMD Radeon RX 5700 XT graphics card, and a RM 750 Gold power supply. I've restarted the system, updated drivers and Windows updates, removed and reinserted the DP cable, reinstalled the driver, used brand new HDMI cables, performed a factory reset, and double-checked that the cables are firmly connected. Even without the driver installed, the black screen persists. I also tested using a TV instead of the monitor, which showed the same problem. It seems the issue isn't related to the monitor but likely a problem with the PC itself. I'm unsure if it's a RAM issue or a general graphics card malfunction. This keeps happening randomly, and most of my friends think it's unusual. Any advice would be greatly appreciated.

It’s better to switch to a different HDMI cable and use another DP port for your GPU because each setup has specific requirements, and mismatches can cause issues.

Do it now and if you suspect a RAM problem, consider replacing the RAM sticks. It’s okay if it takes a moment for the system to boot again after changes—memory training might cause a brief delay.
