Thanks. This is a brand new Dell machine (1 week old). Looking around
on the web, I see many others with the issue. One person reported
that Dell was infuriatingly no help (surprise!), claiming these are "false
positive" errors. I'm moving to China in 3 weeks and have little time
to pursue this with Dell. But I want to avoid my laptop dying in China,
so I'm really not sure what to do.
Sounds like you are in a time squeeze. I'd contact Dell and demand a
new CPU. You can't really afford to have your machine choke on the road.
Best of luck.
