Win Server 2003 - random restart

Zdravim,
Jedna sa o HP server - OS - WIN Server 2003 a problem je ze sa nahodne natvrdo restartuje, tak cca 1 krat za tyzden. Nezostane visiet na BSOD aj ked som automaticky restart zrusil. Proste sa len tak restartuje a ani v eventoch nic neni.

Uz ma z toho boli hlava. Rozmyslam pri tom a hladam uz 5hodin. V hardware to stopercentne neni.
Helfne niekto? Tu je vypis z memory.dmp:

DRIVER_CORRUPTED_EXPOOL (c5)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is
caused by drivers that have corrupted the system pool. Run the driver
verifier against any new (or suspect) drivers, and if that doesn't turn up
the culprit, then use gflags to enable special pool.
Arguments:
Arg1: 00000000, memory referenced
Arg2: d0000002, IRQL
Arg3: 00000001, value 0 = read operation, 1 = write operation
Arg4: 8089c4bb, address which referenced memory
