Is Windows misbehaving on you? Freezing? Crashing? Blue screening? Problems like that can be tough to troubleshoot. They could be hardware-related. They could be software-related. How can you tell? Well, one step you can take is to run two commands in Windows to check for disk or memory issues. The chkdsk command can scan your hard drive for trouble. And the Windows Memory Diagnostic Tool can scan your memory for any glitches. These tools have been around for years and are still available in Windows 10 as they still get the job done.
Check for Disk Errors with Chkdsk
Let’s try out the chkdsk command first. Your hard drive, whether it’s physical disk or a solid state drive, uses a file system to keep track of all its data. Sometimes that file system can become corrupted with errors that affect its performance and reliability. Your disk drive can also develop bad sectors, which are small areas of storage that take up a certain amount of space. These problems often result in unreadable files, among other problems. In both cases, the chkdsk command can reveal errors with your file system or hard disk and hopefully fix them.
You can trigger the chkdsk command a couple of ways. The most familiar method is to run it from a command prompt. In Windows 10 or 8.1, right-click on the Start button and click on the command for “Command Prompt (Admin).” In Windows 7, click on the Start button and type cmd in the “Search programs and files field.” The resulting cmd command appears at the top of the window. Right click on that command and click on “Run as administrator” from the popup menu.
At the command prompt in any version of Windows, type chkdsk to launch the tool and scan your disk drive.
