The correct answer is B. Processor failure. AMI BIOS uses a standardized POST (Power-On Self-Test) beep code system to signal hardware errors before video is initialized. Each beep count maps to a specific failure: 1 beep = DRAM refresh failure, 2 beeps = parity circuit failure, 3 beeps = base 64K RAM failure, 4 beeps =…

Question

Sandra, an expert computer user, hears five beeps while booting her computer that has AMI BIOS; and after that her computer stops responding. Sandra knows that during booting process POST produces different beep codes for different types of errors. Which of the following errors refers to this POST beep code?

Options

ADisplay memory error
BProcessor failure
CMother board timer not operational
DCache memory test failed

Explanation

AMI BIOS uses a standardized POST (Power-On Self-Test) beep code system to signal hardware errors before video is initialized. Each beep count maps to a specific failure: 1 beep = DRAM refresh failure, 2 beeps = parity circuit failure, 3 beeps = base 64K RAM failure, 4 beeps = system timer failure, 5 beeps = processor (CPU) failure, 6 beeps = keyboard controller failure, 8 beeps = display memory read/write failure, and 11 beeps = cache memory error. Since Sandra hears exactly 5 beeps and the system halts, this maps directly to a processor failure. The other options are incorrect: display memory error is 8 beeps (not 5), motherboard timer failure is 4 beeps, and cache memory failure is 11 beeps.
