Memory cannot be 'read'

[Matthew Shaw]

I have done a few searches and people seem to be pointing towards a
defective ram module. Is this true? Also, I got one message the other day "
memory cannot be 'written' ", are these two messages related to a defective
ram module?

I used to get "memory could not be 'read' " messages like once or twice a
month, but in the past few days it has been increasing and twice today I
think it has caused my computer to freeze up, which it never does (I get a
few of those messages in a row, a few windows close down and then a few - I
love that word :) - seconds later the computer freezes).
