4. Expert advice

1.Routine maintenance: Clean the chassis dust regularly, and it is recommended to check the hardware connection status every six months.

2.Data backup: It is recommended to use the "3-2-1" backup principle for important files (3 backups, 2 media, 1 offsite).

3.Upgrade suggestions: For old computers (more than 5 years old), it is recommended to give priority to power supply and hard drive replacement. The recent continued decline in SSD prices is a good time.

4.Maintenance judgment: If the motherboard diagnostic light shows a CPU/DRAM error, ordinary users are advised to send it for repair. Handling it yourself may amplify the fault.

• The new version of Win11 24H2 requires TPM 2.0. Please pay attention to compatibility when upgrading old computers.

Through the above system analysis, when the computer cannot be started, it is recommended to follow the principle of simple first and then complex troubleshooting step by step. In most cases, basic operations will solve the problem. If you try all the methods and it still doesn't work, the core hardware such as the motherboard may be damaged and require professional repair.
