remotely administrated PC crash - how to find the reason?

[Dieter Blaas]

Hi, 
   sorry if this is not the right place for this post but I do not 
know any other:

I administer a PC (WinXP-SP3) remotely via RealVNC (without 
screen, keyboard, and mouse locally attached). From time to 
time this PC crashes and I cannot access it any more. The 
only way to restart it is to ask somebody to disconnect and 
reconnect the power. 

How can I find out the reason for the crashes? 

The Event Protocol for System and for Applications simply 
stoped at the time of the presumed crash and recording starts 
again after reboot. I do not even know whether the PC had a 
BSOD. 

Any input is greatly appreciated,
best, Dieter
