Help with Interpreting and Resolving Irregular Hardware Error Messages on Debian GNU/Linux System

I have a small problem here that I hope your kind help with. Recently these messages started appearing in my notification tray: > Message from syslogd@oldsage at Apr 30 12:25:28 ... kernel:[9655.826192] mce: [Hardware Error]: PROCESSOR 0:6fd TIME 1682871928 SOCKET 0 APIC 0 microcode a3 > Message from syslogd@oldsage at Apr 30 12:25:28 ... kernel:[9655.826180] mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 4: 9000000000020151 Message from syslogd@oldsage at Apr 30 12:25:28 ... kernel:[ 9655.826187] mce: [Hardware Error]: TSC 0 those two messages appear together. But there are no more signs of said error. My system continues to function normally. Although they do not pose direct problems, I am concerned about these messages. They appear from time to time, in irregular periods of several hours. My small computer knowledge does not include the Linux kernel, drivers, or hardware operation. So I pose my question here. What does that mean and if possible how do I fix it? To finish, I leave you the specifications of my PC. As you can see, it is something old.
