Doug,
Thats what I thought, so I swapped my single 512Mb Dimm (PNY) with 2 256MB Dimms (Kingston) and I have the same problem....
I just rebuilt the computer again within the last week. I loaded Office XP, Roxio GoBack, MailWasher and the AT&T Dialer....
Of these, I have Office XP and Roxio running perfectly on a laptop so I'm not looking at those as causing the problem.
However, MailWasher and the dialer and going to come under some real scrutiny this weekend. I'm going to dump MailWasher first
and see what happens....
