I am posting this as nobody else seems to have noticed; but, Samsung's DDR2 memory (PC2-3200, 4200, and 5300) is failing at an alarming rate and what is truly unusual is that they are almost always two to four years old. These are genuine, first on first, Samsung branded parts in Dell's, HP's, Compaq's, and Gateway's so far and, from my 34 years of experience is unprecedented. Good ram tends to stay good!
