技術者が最近組み立てたデスクトップ PC を初めて起動すると、ファンがオンになります。ただし、PC は POST を実行せず、モニターには何も表示されません。技術者が問題のトラブルシューティングを行うために次に行うべきことは次のうちどれですか。
正解:B
If a newly built PC powers on (meaning the fans spin up) but it doesn't POST (Power-On Self- Test) and there's nothing displayed on the monitor, it's most likely a hardware issue rather than something related to the operating system or monitor. The most common troubleshooting step in this scenario is: Reseat the system memory. Ensuring that the RAM modules are properly seated can often resolve POST issues. It's not uncommon for RAM to be slightly unseated during assembly, or for there to be some obstruction (like dust) in the RAM slot.
