Vista hangs unexpectedly, how to find a cause of hang-up?

Hi, all.

I installed Windows Vista about three weeks ago. From the very beginning it
hangs two or three times a day. I cannot find anything that I can suspect.
There is no overclocking, antivirus (KIS) is uninstalled. The only things I
see is the records in the reliability and performance monitor: "Disruptive
shutdown" in the "Miscellaneous Failures". I'm not doing anything specific
before each hangup - working in some program, developing applications,
surfing internet or watching a movie. It hangs sometimes when the PC is
idle. It looks like CPU is not overheated because settings in the BIOS set
to signal about overheating at minimum suspicious temperature - 60C, the CPU
temperature rarely goes higher than 50C and almost never hit 55C. What is
important it is that in same conditions with same hardware there were no
problems under Windows XP. Count of hangups of Windows XP was three..five
times a year.

I'd like to know how to detect cause of hang-up? Is there any common
practices?

Hello,
I had the same problem as you. I investigated during one week because
hang-up came +/- every 7 hours. Finally after a lot of bios and Vista
drivers update I had the chance to think to disconnect Bluetooth dongle
and surprise .... finally a stable situation (I see that you use a BT
dongle).
For my PDA synchronization I used the Vista native BT stack. Now I
installed the driver coming with my dongle (Toshiba stack) and now my PC
is stable with Bluetooth dongle.
I hope that could help you. Regards
