MS SQL server napaka in računalnik zmrzne

Torej, imamo računalnik, kjer laufa MS SQL server za eno aplikacijo.
Računalnik je pred časom začel random zmrzovat.

Prvo sem sumil hardware, vendar sem po pregledu Event viewerja spoznal, da so časi napak in "freezanja" usklajeni.

Sistem je WinXP SP1:

Napaka pod rumenim klicajem:

The description for Event ID ( 19011 ) in Source ( MSSQL$INSTANCE1 ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: (SpnRegister) : Error 1355.

Napaka po rdečim opozorilom:

Hanging application ***.exe (program, ki zapisuje v bazo), version 3.0.0.319, hang module hungapp, version 0.0.0.0, hang address 0x00000000.

Ima kdo kakšno idejo?
