It comes a time when your computer starts trowing on you some errors, restarts, blue screens of death and the only thing left is to start checking what is causing the problems.
One of the first things you should check is if you have a faulty RAM module.
The best tool for testing memory modules is memtest86+.
Where you can find Memtest:
- On HirenBootCD.
- On almost every linux distribution LiveCD.
If you remember the previous tutorial on this site about Puppy Linux on a bootable flash disk drive, the thing is, we don’t have memtest86+, but we can install it on the good old trusty linux on a stick to use memtest on any computer that can boot from USB.
We assume you have the Puppy Linux installed on a USB flash drive and we start from there:
- Boot your computer on Puppy from your USB drive.
- Go to Menu > System > Grub4Dos bootloader config.
- Select your USB drive and press OK.
- On the next screen just press OK to install GRUB bootloader (GRUB is menu system that lets you choose the OS/drive/app you want to boot into).
- Open a web Browser and go to the Memtest download website.
- Download the 3rd link (as of Memtest86+ V5.01 (27/09/2013), the one that points to memtest86+-5.01.bin.gz
- On the bottom of your Puppy Linux desktop open the root of your Puppy USB drive (mine is sdf1). Leave this window open.
- At the top of the Puppy Linux desktop open the file app (the one with a home icon on a folder).
- Press the Downloads folder. Here you will find the downloaded Memtest file.
- Right click and Rename. Rename it to memtest.bin.
- Now drag the file from step 10 to the window on step 7 to move the memtest.bin file there.
- Now, on the location you moved the memtest.bin file (your sdfx location=the root of your USB drive) you can see menu.lst (the menu for the GRUB bootloader).
- Open menu.lst and after the entry for Puppy linux, paste this (without the 14.):
- # memtest+
title memtest86+ v5.0.1
- Close the file and reboot Puppy.
After rebooting the Puppy Linux USB drive, you will get the GRUB bootloader with some entries:
- Windows (if you have it installed)
All entries shoot boot the appropriate OS/apps but to test our installation select Memtest and wait until it checks your RAM modules. Press ESC when done.
There you have it, you can test the memory on any USB bootable computer in the world.
Have fun and if you have questions, please shoot!
