3.9.6 Memory Troubleshooting
b
After installing two memory modules, you power on the system to check for errors. You find that the BIOS program recognizes only one of the memory modules. While troubleshooting this issue, which of the following is BEST to try first? A• Reboot the computer and run memory diagnostic tests on the memory. B• Make sure that both modules are seated properly in their slots. C• Change the memory timings in the BIOS to a slower (higher) setting. D• Scan for new devices in Device Manager; enable any disabled memory modules. E• Return both modules for a replacement.
a
Match the critical time with its corresponding cause. Incompletely or improperly doing this can cause errors that appear to be memory-related. A• Hardware installation or removal B• Software installation C• Memory upgrade D• First boot of a new computer
d
Match the critical time with its corresponding cause. Memory is not properly seated or missing/the motherboard is defective. A• Hardware installation or removal B• Software installation C• Memory upgrade D• First boot of a new computer
c
Match the critical time with its corresponding cause. The memory is not compatible and was not installed and configured properly. A• Hardware installation or removal B• Software installation C• Memory upgrade D• First boot of a new computer
b
Match the critical time with its corresponding cause. This event can require more memory and can cause problems if there is not enough memory when it occurs. A• Hardware installation or removal B• Software installation C• Memory upgrade D• First boot of a new computer
b
Which of the following is an error detection technique that can also correct the error? A• EDO B• ECC C• Non-parity D• Parity
a
Which of the following is an error detection technique that can detect errors with only one bit? A• Parity B• Non-parity C• EDO D• ECC
adf
Which type of software-generated problems can indicate that a software bug is causing a memory error? (Select THREE.) A• General-protection fault B• Parity interrupt C• Incorrect memory count D• Page fault E• Registry error F• Exception error
b
You are attempting to boot a new system. The boot fails, and the system sounds a beep code. Which of the following describes the MOST likely cause of this error? A• The POST failed to recognize all of the memory. B• Either no memory is installed or the memory was not detected. C• The new memory is not compatible and was not installed and configured properly. D• Either a card/memory module is not seated properly or the system includes unsupported memory.
c
You are in the process of configuring a new computer. The motherboard has four memory slots and supports dual-channel memory. You install two memory modules. When you boot the computer, the BIOS recognizes both modules, but the memory is not configured to run in dual-channel mode. What should you do? A• Change the CAS latency to a higher setting. B• Replace the memory with dual-channel capable memory. C• Move the modules to the correct motherboard slots. D• Add continuity modules to unused memory slots.
b
You have installed a new computer with a quad-core 64-bit processor, 6 GB of memory, and a PCIe video card with 512 MB of memory. After installing the operating system, you see less than 4 GB of memory showing as available in Windows. Which of the following actions would MOST likely rectify this issue? A• Flash the BIOS. B• Install a 64-bit version of the operating system. C• Update the memory controller driver in Device Manager. D• Disable the AGP aperture in the BIOS.
d
You have just built a new system from scratch. You turn the computer on, but the system boot fails and sounds a beep code. Which of the following is the MOST likely cause? A• Incompatible memory was installed B• New and old memory have been mixed C• The system includes unsupported memory D• Memory not installed or not detected
d
You just replaced the motherboard, CPU, and memory in your computer. Now your computer will not start. You press the power button on the system case, but nothing happens; there are no sounds or lights. What should you do? A• Make sure a keyboard and mouse are plugged in. B• Connect the processor fan to the motherboard. C• Make sure the memory is properly seated. D• Connect the power button to the motherboard.
