I had a close call which ultimately turned out to be good news this week: the RAM in my personal computer died, and thus so did my PC. This is not normally considered Good News, but the RAM happens to be Crucial brand RAM, it's backed by a lifetime guarantee. I called them up, they shipped me a new stick, and I ship the dead one back to them. The only cost to me is shipping of the old stick to Crucial. Fantastic company, great customer service; don't buy RAM anywhere else.
