genoemd. Als u de pc niet kunt opstarten of geen POST kunt uitvoeren, kunt u het beste eerst deze zelfdiagnose uitvoeren. Wanneer de zelfdiagnose wordt uitgevoerd en er foutcodes worden weergegeven, bent u al een eind op weg om het probleem op te lossen. Wanneer de zelfdiagnose niet kan worden uitgevoerd, is er iets grondig mis met de hardware. Wanneer

er een foutcode wordt weergegeven, kunt u gemakkelijker vaststellen waar de fout zit en het hardwareprobleem oplossen. Als de zelfdiagnose slaagt, zijn alle hardwaretests voltooid en moet u het probleem bij de software zoeken. De PSA Diagnostics hebben een tekstinterface, terwijl de ePSA (voorheen PSA+) Diagnostics een tekstinterface of een grafische interface (GUI) hebben (lijsten met tekst of afbeeldingen/grafieken en tekst op het scherm bij het doorlopen van elk van de tests.) De tests zijn zeer uitgebreid. De ePSA-testprogramma's omvatten zowel alle tests uit het oudere PSA-pakket als extra ondersteuning voor: MpMemory-algoritmen. Computercontrole-uitzondering. Systeemkaartdiagnostiek, samengevoegd in één categorie. Opmerking: Afhankelijk van hun productiedatum bevatten laptops PSA of ePSA Diagnostics. En desktops hebben de desktopversie van ePSA Diagnostics. U kunt de resultaten gebruiken om te bepalen of en waar een hardwarefout is opgetreden. Opmerking: De diagnose voor laptopsystemen mag niet worden uitgevoerd wanneer het systeem zich in het dockingstation bevindt of het interne LCD-scherm zich in de gesloten positie bevindt. Als u dit toch doet, kan onterecht een fout worden gerapporteerd. Meestal is dit de fout 2000:0326 of 2000:0321.

starting the remainder of the boot process. If the computer passes the POST, the computer may give a single beep (some computers may beep twice) as it starts and continue to boot. However, if the computer fails the POST, the computer will either not beep or generate a beep code that tells the user the source of the problem. If your computer has an irregular POST or a beep code not mentioned below, follow the POST troubleshooting steps to determine the failing hardware component.
