Testing with Memory Diagnostics Tool:

Windows Memory Diagnostics Tool is the better and convenient way of testing memory, and it is already included in your basic Windows package. So, you can start it right away and don’t need to bother by installing third party software. Remember that the memory test itself runs independently from Windows in order to minimize the memory load, due to which you need to reboot your PC in the process.

Hold down the Windows Key + R to open up the run prompt in order to initiate the test process. Then, type “mdsched” in the empty field and hit Enter. After doing so, a new window will pop up asking you to restart your PC. Restart your PC and wait for Windows Diagnostics Tool to load. By default, the tool will start its standard scanning process automatically. Depending on your CPU performance and memory size, scanning process may take a little while to complete.

After the completion of the test, the tool will automatically restarts your PC and throw you back into the normal Windows interface. Search the bottom right area of your taskbar for overviewing of the testing results. If errors have been found, then the tool will attempt to pin-point their origin and walk you through solving the issue.

Testing with Memtest86:

When compared to Windows Diagnostics tool, Memtest86 is often considered as the more thorough solution. Memtest86 comes in the form of an ISO image, so that you need to burn it on a disk with another program before being able to use it. Additionally, you might need to have a look into BIOS settings to ensure that your boot order prioritizes the disk drive in favor of your hard drive, thus making sure Memtest86 won’t simply get skipped while booting.

If everything is in order and ready to go, then restart your computer with the bootable disk to launch Memtest86. Once inside the main menu, press 1 and Enter for loading the latest runtime version. The testing process itself will begin automatically after a couple of seconds and go through eleven dedicated routines, testing your RAM’s ability to save data discretely as well as safely. If all tests have completed processing without any complications, then your memory modules seems to be fine and the problem lies probably elsewhere. If in case, there are errors, then swap out your RAM modules to find out which one is causing the problem and try plugging it into a different slot. If issue persists, then the module is likely faulty and need to be replaced.

In case, if bad memory is in the hard disk drive and if huge number of bad sectors have been formed on your hard disk drive, and you are unable to fetch your data, then don’t worry! Just make use of Remo Recover software for recovering data from hard drive with bad boot sector with great ease.
