My Studio XPS 9100 occasionally stops. When it stops, the screen is unchanged, but the cursor doesn't move. If I'm streaming audio, it stops. The keyboard LED are lit, but I can't change anything, like the Caps Lock. After some period of time, usually a minute or less, sometimes longer, it starts working again exactly where it was. The streaming audio picks up right where it left off, but a few seconds later, it times out. It's as though the clock stopped ticking, then started up again. A few times I gave up waiting and cycled power.
I've run diagnostics and nothing showed up. Any ideas?
