Hi Nels,
Thank you for your posting.
Before moving on, could you please help us confirm following points?
1. Does the issue occur since clean install? Did you encounter same
issue before?
2. Did you make any changes or install any software/hardware on the
computer recently?
3. Did you install the latest Windows XP Service Pack? (For more
information: KB326719 Screen Saver May Not Start in Windows
XP(
http://support.microsoft.com/kb/326719))
Mostly, the issue is caused by a software/hardware conflict problem. Could
you please take a Clean Boot to test the issue? If the issue disappears in
Clean Boot, we can use a 50/50 approach to quickly narrow down which entry
is causing the issue.
