Over the past 3 days my PC has automatically rebooted at least 5 times. It has also frozen twice (with the screen filled with garbage - a gazillion repeats of a small section of the last active window, I think). No BSOD.
I see no log entries reporting anything at the time of failure, but on reboot it logged
Log Name: System
Date: 8/24/2010 9:28:02 AM
Event ID: 41
Task Category: (63)
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

The previous system shutdown at 9:26:14 AM on 8/24/2010 was unexpected.
The PC is fairly new - 6 weeks old - and has been running fine until now (except for occasional hangs during shutdown of "sleep").

Any suggestions for where I begin debugging this?
FYI, The PC was custom-built by NCIX (aka. Netlink Computer Inc.) of Canada.
Windows 7 x64 Home was pre-installed but I upgraded to PRO a month ago.
