BSOB at shutdown or restart- any ideas?

[cipher 0]

i get a BSOD od restart of shutdown-

 

any ideas anyone- the BSOD says " IRQL_NOT_LESS_OR_EQUAL"

 

it seems to start when i installed 12.90 Win2K drivers fr my Elsa 920. May try some other ones- anyone know which GF drivers work for sure in XP?
