A failing power supply and/or off-spec memory module can cause
unpredictable lock-up's.
I use an inexpensive ATX power supply tester for quick pass/fail testing:

I use memtest86+ for checking RAM:

Run memtest86+ for at least 12 hours; better 24. I've seen machines
with infrequent lock-up problems pass an hour or more of testing, only
to fail once or twice in later hours.
If your new computer fails either of the above, return it.
If the memory and power supply test out okay, then understand that the
whole point of the Debian "testing" release is to find bugs. Here is
your opportunity to do so.

If you're going to re-install, a fresh ISO would be a good idea. I
typically run amd64 on compatible hardware, but i386 with PAE (default)
supports more than 4 GB of RAM too. Installing and running Wheezy for a
week or so should narrow the possibilities.
