Information regarding Random Access Memory (RAM) function and troubleshooting via Windows diagnostic tools has been detailed. RAM acts as a volatile, high-speed workspace necessary for multitasking and smooth application performance in computers and smartphones.

To address system instability such as freezes, random restarts, or the ‘Blue Screen of Death’, the Windows Memory Diagnostic tool can be used. This utility identifies hardware failures by writing and reading data to ensure integrity. Users can access the tool via the ‘mdsched.exe’ command. While the initial reports focus on the tool’s basic operation, subsequent details clarify that Windows 11 offers both standard and extended testing options to provide more thorough checks if initial results are inconclusive.
