Hello,
After assembly this system by myself and try to boot up system. There is no signal output, only CPU fan rotates, even change another monitor. Also no speaker beeping. USB keyboard mouse no function.

Is there anything I can do to for this case?
All brand new 2400G CPU and onboard output.

Thanks,

Dear HaKaN,

Greetings, this is ASRock TSD.

According to your question, we have some suggestions for you to check your system:

1. Please refer to user manual page.21 to clear CMOS.

2. Only install one stick memory to each DRAM slot by turns to verify.

3. Make sure the monitor input signal is properly configuring for the graphics output. (HDMI, VGA, DP)

4. If possible, please install another memory, CPU to verify.

Thanks!

All the best,
ASRock TSD

The final action is replace a new board and the problem is fixed.
So the root cause is faulty board.
