A user reports that their Windows 11 computer is experiencing frequent system crashes and blue screen errors. A technician suspects a memory issue. Which Windows command-line utility can be used to check the system's RAM for errors?
- Asfc
- Bchkdsk
- Cmemtest
- Dmdsched.exe
Show answer & explanationAnswer & explanation
Correct answer: D. mdsched.exe
mdsched.exe (Windows Memory Diagnostic) is the built-in Windows tool specifically designed to check the system's RAM for errors. It reboots the computer and runs a series of memory tests.
Why the other options are wrong
- A. sfc (System File Checker) is used to scan and restore corrupted Windows system files, not to check RAM.
- B. chkdsk (Check Disk) is used to check and repair errors on a disk volume, not RAM.
- C. memtest is a common third-party memory testing tool, but not a built-in Windows command-line utility.

- Requires a system reboot to run.
- Performs various memory tests.
- Can identify hardware-level memory issues.
