I'm investigating the causes for my 2-year-old Samsung laptop running slow and sometimes hanging under very slow stress. I have some friends which had the exact same model as mine and had to send their laptops back to Samsung, all with similar problems - and each received a different diagnosis. Unfortunately, this is not a possibility for me, since it's not under warranty anymore.
I had my laptop dual-booting with Ubuntu 12.04 and Windows 7, and I was experiencing the problem with both OSes. Tired of Ubuntu, I decided to give Fedora 19 a try - but even with a fresh install I'm still sometimes very slow performance. However, given enough reboots, eventually it runs smoothly.
For all that, my suspicion is that there's a hardware problem. What are the most likely candidates to be causing the problems and which tools can be used to investigate them?

1maybe you have a HW-Test integrated in your BIOS which can test your RAM and other things? – Gotschi – 2013-12-11T20:08:20.660
1Have you opened it up and cleaned out all the heatsinks and fans? – Mokubai – 2013-12-11T20:46:56.093
What were the diagnoses in the cases of your friends? What is slow on the computer -- disk? (high activity during slowness, weird noises), graphics? (slow graphic operations like moving of full window), overall? -- Is the temperature of some parts of the computer too high? Is the fan working correctly? Is not there too much of dust inside? (the comment above) -- Try to remove / disable (e.g. in BIOS) / replace some hardware components: HDD (boot live OS), CDROM, RAM, wifi... – pabouk – 2013-12-11T20:47:44.550
