About this tag
The power-on-self-test (POST) is a diagnostic process that a computer performs immediately after it is powered on to verify that essential hardware components are functioning correctly. On Windows 8 systems, users may find that the POST screen is hidden or replaced by a manufacturer logo, making it difficult to view diagnostic messages. However, it is often possible to enable POST display through BIOS settings or by using specific key combinations during boot. POST results can also be communicated through beep codes, which vary by BIOS manufacturer such as AMI. These beep codes indicate specific hardware failures, such as memory errors or processor issues, helping users troubleshoot problems without a display.
