About the problem that F2-220 cannot start normally after reinstalling the system

[semsdawn]

In the past month or two, the TOS5 system running on my F2-220 has had many problems. Sometimes, after booting up, I can access smb and ssh, but I can't enter the web interface; sometimes, the machine can't start normally after booting up or restarting (usually the buzzer will sound once after the self-test is completed, but when there is a problem, the buzzer is completely silent).
I tried to reinstall the system and downloaded the TOS5.1 system. When the web page after the installation was completed prompted that it was restarting and the three-minute countdown was on, I found that the system was completely stuck from the display output (I used a 12p interface to transfer a VGA). The following picture is the last output before it was stuck:



Before this, I also tried to install the omv7 and omv6 systems, and the problem of not being able to complete the self-check and start normally after powering on or restarting occurred.

This time I tried to reinstall the system again, and it still didn't respond at all. I waited for more than 20 minutes, but still nothing happened.
