Reboot of PC with Event ID 1001 (bugcheck F4)

[moli34]

Hi!
I have a PC under windows XP SP3 which has rebooted several time in two days.
I do not have any monitor on this PC, so I'am not able to say if there is any blue screen during the occurence of the problem.
Anyway for each reboot of the PC, an event ID 1001 (bugcheck F4) appears in the events log of windows (see screeshot attached).
I attach also the minidump saved during the problem.
I suspect a hardware problem, does anybody have some clue about the source of this problem?
Thanks in advance for your help.

jo.

One of your minidumps was unreadable but the other four were all the same error: 0x000000F4: CRITICAL_OBJECT_TERMINATION
One of the many processes or threads crucial to system operation has unexpectedly exited or been terminated. As a result, the system can no longer function. Specific causes are many, and often best resolved by a careful history of the problem and the circumstances of the error message.



All cited the same csrss.exe and this is the Windows client server run-time subsystem driver that handles Windows and graphics functions for all subsystems. it is very important.

Question: What are you specifically doing when these BSODs occur?
