A user reports that a workstation fails to complete boot up and repeats a series of two beeps over and over. The user states that the workstation had been displaying BSOD errors after running…

Video adapter failure typically produces beep codes associated with display errors (commonly one long and two or three short beeps) and would not explain BSODs triggered specifically by running multiple applications.

During POST (Power-On Self-Test), the BIOS issues beep codes to signal hardware faults when video output is unavailable. Two repeating beeps on many BIOS implementations indicate a memory error. This is corroborated by the prior BSOD symptoms occurring when running multiple applications simultaneously, which stresses RAM, making memory failure the most consistent explanation for both the POST beep code and the crash pattern.

Power supply failure would more commonly result in failure to power on, random shutdowns, or no POST activity at all, rather than a specific and consistent two-beep code.

CPU failure would typically prevent the system from completing any POST sequence and would not produce the selective, load-dependent BSOD behavior described.
