What causes the invalid_mdl_range BSOD?

From the complaints of some readers, we gather that any of the following may trigger the BSOD on Windows:

• Malware or virus infection – If your system files, particularly those related to memory management, get corrupted due to malware or viruses, it can cause the BSOD error to occur.
• Memory overclocking – When the clock speeds are increased beyond the memory’s capacity, it can lead to memory-related errors like the BSOD error.
• Software conflicts – When software applications or drivers clash, it can disrupt memory management and cause the error to occur.
