I take it that no memory error shows up during boot. The BIOS should tell you if there is a genuine memory problem. Also, look in ME's System Information (Start/Programs/Accessories/System Tools/System Information); go to Hardware Resources/Memory. That will list a bunch of memory addresses (but not all); see if any are not OK and see if the one Norton lists is among those which are said to be OK. If neither the BIOS nor System Information tells you that the address is faulty, the problem is probably with Norton not with memory. Apparently no separate memory testing program is shipped with the 8100's (I have one and could not find any such program anywhere). However, to be certain, you should check everything out with tech support; an email to them may be sufficient; if you have to phone try around 1:30 pm PST (weekdays) or early AM (EST); at those times I rarely wait more than about 5 minutes.

Also: afterthought: a memory module in my brain is being half way activated. Go to the Symantic Web site (www.symantec.com); then whenever you can through their morass, do a search on appropriate subjects ("memory errors", "memory", "memory addresses", and the like). I have a faint memory that there is a document somewhere in that morass which addresses the issue.
