Hi,

I installed VirtualBox a few weeks ago, but I've been having this problem. VirtualBox often reboots my computer, without any warning, not even a BSOD. I just hear a clicking sound from inside the box of the PC, and next thing the monitor is showing the initial BIOS welcome screens and booting my host OS.

This happens only if I have first reverted to a saved snapshot of the Vista guest, and then started the virtual machine. If I just power it off and then start the virtual machine, it doesn't happen.

My host os is XP with SP3. My guest os is Vista.

i'm uploading the log files.

this is Vista-2009-04-29-13-48-41.log

this is the last one

Check your Host event logs first.
