SiSoftware Sandra Lite shareware by SiSoft
I’ve been using Sandra since way back when, the utility has a lot of nice functions built into its easy to use interface. This program gives you a wealth of information about your computer and has some nifty utilities to benchmark your individual hardware components, such as CPU, RAM, etc. I use this program often to benchmark a system if the customer complains it is running slow to narrow down where the performance bottleneck is coming from.
