Yes it is.

Weird, irreproducible problems like this are often the sign of some kind of
hardware failure. The first thing that comes to mind is bad memory. I'd
suggest testing it somehow (maybe someone will follow up and recommend a
tester), and replacing it if there is a problem. You might want to back up
your data in the meantime.
