AIDA32 - Worldwide Sysinfo Tool: This little gem of a tool will tell you more about your system that you thought there was to know.

It generates a big report (2MB as an HTML archive) with every possible piece of information on your machine: motherboard, chipset, BIOS, running processes, user accounts, installed database drivers, fonts, every single physical slot and what card occupies it, etc. Run this just once and save the report and you’ve got a great reference when you’re trying to debug some problem.
