技術者が新しいマザーボードをインストールした後、コンピューターが起動せず、POST に失敗します。技術者は、電源が期待どおりに機能していること、および CPU が正しくインストールされていることを確認します。技術者は次にどの手順を実行する必要がありますか?
正解:C
A common reason for a POST failure after a motherboard installation is improperly seated RAM. The system requires working memory to successfully complete POST. Reseating (removing and reinserting) the RAM ensures it's making proper contact with the motherboard. * Option A: Flashing the BIOS is not possible if the system won't POST. * Option B: A dead CMOS battery can cause BIOS settings to reset, but it usually won't prevent POST entirely. * Option D: Reinstalling the old motherboard is premature - basic troubleshooting steps should be completed first.
