Linux setup steps/Memory test
From Nick Jenkins
First run Memtest86+ on the machine overnight, to test that the CPU and memory are error-free. Also run a CPU stress test for 5 to 10 minutes to check CPU is reliable and adequately cooled. The easiest way to download and run these memory and CPU testing tools is with the Ultimate Boot CD.
If the machine does not pass memtest and CPU stress tests without any errors or warnings at all, then do NOT proceed any further until this is rectified.
