That certainly doesn't sound positive. Any memory errors at all are a fail in this test. It's hard to imagine there isn't
something in the Event Logs, specifically the Windows System Event Log.
But just the fact that your laptop is beeping is a fail. That is not a common problem. I'd definitely return it, even if I couldn't exchange it for a new unit and had to accept a refund. You don't want this new defective laptop to become YOUR problem...
