Here's how it works:
  1. Anybody can ask a question
  2. Anybody can answer
  3. The best answers are voted up and rise to the top

Here's what would be ideal:

  1. A list of all the hardware components potentially found in one's computer
  2. A method (or list of methods) for testing each of these
  3. The accuracy of these methods

My personal requests are:

-How to test your motherboard
-How to test your wireless receiving aperatus
-How to test CD/DVD RW drive
-How to test your laptop battery
-How to test your Heat sink(s) ?
-How to test the effectiveness of your fan(s)

Favorite answers: OS-independent tests which GUARANTEE the concerned hardware works PERFECTLY

No test can ever guarantee that anything works PERFECTLY... – Shinrai Aug 16 '10 at 14:40

No test suite can guarantee that anything works perfectly, they can only tell you if the computer passed the tests.

This Live-CD does some of it, I have never seen anyone test the CD/DVD or wifi. But any live-cd meant for ordinary use should allow you to test that manually.


StressLinux is a minimal linux distribution running from a bootable cdrom (LiveCD) or via PXE. Stresslinux is dedicated to users who want to test their system(s) entirely on high load and monitoring the health.


  • stress 0.18.1 (A tool to impose certain types of stress on a POSIX system.)
  • CPUBurn 1.4 (CPU maximum load (heat) stability test)
  • CPU Burn-In 1.00 (CPU burn-in test)
  • nbench 2.2.1 (CPU test suite)
  • iometer 2003.12.16 (I/O performance meter)
  • hddtemp 0.3beta11 (A program to display the temperature of your hard drive.)
  • lm_sensors 2.8.7 (LM78 and other hardware monitor drivers.)
  • busybox 1.0.0rc3 (Single small executable which contains common UNIX utilities)
  • lshw A.01.07 (Hardware lister)
  • bonnie++ 1.03a (Hard drive benchmark)
  • netio 1.23 (Network benchmark)
  • smartmontools 5.32 (S.M.A.R.T. drivetests)
  • x86info 1.12b (CPU information)
  • memtest86 3.1a (A stand-alone memory diagnostic)
  • memtest86+ 1.15 (An other stand-alone memory diagnostic)

@Nifle Are there any risks to the hardware associated with using stresslinux? For example, could pushing my CPU to the limit possibly break the CPU or melt any surrounding part? – Shawn Aug 16 '10 at 20:44
@Shawn - No. What it can (in theory) do is push any partly defective part far enough so that it fails completely. It can't destroy or harm a functioning computer. – Nifle Aug 17 '10 at 16:05
@Nifle So if I suspect some parts of being defective, should I run the tests? – Shawn Aug 17 '10 at 21:24

If money is no object the PC Doctor testing suite is pretty damned good. It's pretty damned expensive though...

If I had that much money, I would buy a new computer :D – Shawn Dec 6 '10 at 4:07
@Shawn - No debate there. ;) – Shinrai Dec 6 '10 at 15:47

Or a very easy way: go to a computer store and pay a small sum, and they will do this test for you. If all else fails, download a simple tuning program which can typically give the computer a test.

If you have a HP computer they normally have a POST test and some diagnostic tools built-in to them, telling you if something fails. AKA the S.M.A.R.T test for hard drives.

POST and SMART are completely different things. The first is run only once at each startups (and takes seconds), the other is a monitoring performed during the whole lifetime of the HDD. – Dmitry Grigoryev Jul 23 '15 at 6:35
