You could also download and burn a bootable CD copy of knoppix.

Knoppix also has the memtest option as well--at the boot prompt, just type in "memtest" without the quotes, and it will run the memtest86+ program.

Either this month's or last month's copy of Linux has SimplyMepis CD attached to it. Works well.
