During a routine hardware upgrade, a technician installs a new CPU into a workstation. After powering on, the system emits a series of long beeps and the screen remains blank. What is the most likely cause?
A technician is building a new gaming PC and wants to ensure the CPU can handle heavy multitasking and overclocking. The motherboard supports both Intel and AMD CPUs, but the technician is unsure which CPU features to prioritize. Which CPU characteristic is most important for overclocking stability?
A technician is replacing a CPU in a server that uses a LGA 1151 socket. After installing the new CPU and applying thermal paste, the system fails to post. The technician notices the CPU cooler is not making full contact with the CPU. What is the most likely consequence of this poor contact?
A customer reports that their desktop computer intermittently freezes and emits a high-pitched whine. The issue occurs more frequently under heavy load, such as when rendering video. Which CPU-related feature is most likely causing this symptom?
A technician is troubleshooting a system that experiences random lockups and blue screens. The technician suspects a CPU issue but has already run a stress test without errors. Which diagnostic step should the technician perform next to isolate the problem?
A technician is configuring a server that requires maximum memory bandwidth for virtual machines. The motherboard has four memory slots and supports dual-channel architecture. The technician installs two 16 GB DIMMs. Which configuration will provide the best performance?
A technician is building a new workstation for a graphic designer. The user needs fast single-threaded performance for Adobe Photoshop. Which CPU characteristic should the technician prioritize?
A user reports that their computer intermittently freezes for a few seconds during normal use. The technician checks Event Viewer and finds 'WHEA-Logger' errors related to the CPU. What is the most likely cause?
A user complains that their computer is running slowly, especially when opening multiple browser tabs. Task Manager shows the CPU is at 100% usage constantly, even when idle. Which of the following is the most likely cause?
A technician is troubleshooting a system that randomly restarts under load. The CPU temperature never exceeds 75°C, and the power supply is rated at 750W. Which of the following should the technician check next?
