Your Own Computer Hardware Diagnostic Hacks: UBUNTU

Last time I shared hardware related diagnostic hacks for Windows OS users.

So I’m back with the diagnostic hacks for Ubuntu users.

So let’s get started–

Best Computer Diagnostic Tools For RAM:

For Ubuntu:

Memtest86+ (Also available for Windows)

This is an inbuilt memory checking tool for Ubuntu Linux. To start the Memtest86+:

1. Restart your machine. During the restart process, press and hold the SHIFT key at the boot screen.

2. You end up on the Grub screen, where you’ll see memtest86+.

3. Navigate using the arrow keys to memtest86+ and press Enter. The serial console option is for Remote Acess.

4. The RAM test process will take a few minutes to complete.

Best Computers Diagnostic Tools For Hard Drive:

For Ubuntu:

Ubuntu has an inbuilt S.M.A.R.T. utility to deliver the hard drive information to you. To access the utility:

1. Click the Ubuntu button and type Disk.

2. In the Disk utility, select your hard drive in the left pane.

3. Click the button (having 3 horizontal lines) in the top right corner of the Disk utility. Click SMART Data & Self-Tests. You can also press CTRL+S to access the same (you need to be on the Disk Utility).


Best Computer Diagnostic Tools For CPU:


Prime95 (Works for Intel/AMD): 

It is a CPU stress test tool designed to give a 3rd-degree torture to your processor. It also supports OS X.


It’s an ugly looking brother of the Prime95. By ugly, I mean it works on the Ubuntu command line.


For the command line lovers, CPUburn is also a good stress testing utility.

Important: Stress testing utilities put extra load on your machine to test its stability. Please gain enough knowledge about stress testing and the tool you’re using to do it (especially for the command line). Don’t do it if you don’t know much about it.


All-In-One Computer Diagnostics Tools

For Ubuntu:


If you have Ubuntu installed on your machine, then an inbuilt tool Checkbox does the job of finding hardware errors in different components of your machine.


System Information Tool For Ubuntu:


It is a great utility for accessing system information on Ubuntu operating system. An alternative Device Manager also exists for older Ubuntu versions.
