After upgrading the CPU, no display appears.
I tried to upgrade from an i5 8400 to a i7 9700k. I checked the website and confirmed compatibility for my Gigabyte Z370 HD3P. Updated the BIOS software accordingly, installed everything, and powered on the PC. After about 20-25 seconds, the monitor didn’t display anything, then it would shut off and restart repeatedly. Upon closer look, I found bent or broken pins in the CPU socket—similar to what was present when I removed the old CPU. Even after replacing the old one, the problem persisted.
What operating system are you using? - On Ubuntu it's standard. The key is to install the OS, update Software Center, add the NVIDIA PPA. Shut down the PC, put the GPU in, and switch drivers to NVIDIA if it doesn't recognize the keyboard. If that fails, turn off the PC and gently tug on all cables—sometimes a loose connection helps. Make sure your HDMI cable is properly seated in the socket or not bent.
If you have a Windows system, consider these steps:
1. Go to BIOS settings and enable integrated graphics.
2. If that doesn't work, turn off the PC and carefully check all cables—especially the HDMI connection.
3. Ensure the HDMI cable is correctly inserted and undamaged.
4. Look for debug LEDs if they appear.
5. If bent components are suspected, the board may be damaged.
Windows, no output appears so I can't perform the BIOS test. Everything seems to light up and it powers on normally. I'll revisit the cables later, but I'm pretty sure this isn't the issue.
