SiSoftware Sandra Lite (the System ANalyser, Diagnostic and Reporting Assistant) is a non-commercial freeware.
SiSoftware Sandra is an information & diagnostic
utility. It should provide most of the
information (including undocumented)
you need to know about your hardware,
software and other devices whether
hardware or software.
It works along the lines of other
Windows utilities, however it tries to
go beyond them and show you more of
what's really going on. Giving the
user the ability to draw comparisons
at both a high and low-level. You can
get information about the CPU,
chipset, video adapter, ports,
printers, sound card, memory, network,
Windows internals, AGP, PCI, PCI-X,
PCIe (PCI Express), database, USB,
USB2, 1394/Firewire, etc.
Since a download link for it is somewhat hard to find on sisoftware.net, here it is on filehippo.
