I'm running Google Chrome (6.0.427.0 dev) on Windows 7 Home Premium 64-bit (AMD Phenom 3.00 GHz, 8 GB RAM). The computer lockups hard after running Chrome for about five minutes. The lockup happens whether Chrome is actually being used to browse web sites or it is just idling. No programs can be started or interacted with when this happens. The computer must be power-cycled to recover.

The lockup happens regardless of which web sites are being browsed.

The system event logs do not show any events around the time when the lockup transpired.

All other applications run just fine on this system. In fact, Chrome ran without issue for several months on this system (the system was brand new 03-2010).

I also run the same version of Chrome on other computers (Windows XP SP3) without issue.

I've come to really like Chrome and use it as my default browser whenever possible.

What could be causing Chrome to cause the system to lockup as it does? Does Chrome have any logs that aren't part of the Windows event log? Does Chrome have a debug command line switch that might reveal more about what happens?
