I realize that you're making a point, but, since he asked the question in the first place, we can only assume that he is not as familiar with the concepts involved as we are. So, there is no direct correlation between number of memory errors and how often your computer will crash. Even one error could have dire results, if, for example, it were used when writing some registry data out and it ended up corrupting the registry. Your computer might not even crash, but the next time it did, for whatever reason (we are talking Windows, here, right ), it might be corrupted beyond bootability.

To sum up, memory errors are bad, very bad.
