BSOD at restart after installing NAV 2009

I've been getting a blue screen with the following error messages:

 

IRQL_NOT_LESS_OR_EQUAL

and 

*** STOP: 0x0000000A (0x0000000000000880, 0x000000000000000C, 0x0000000000000001, 0xFFFFF80001C78A15) 

 

My computer info:

 

HP brand new laptop dv3t

running Vista Home 64 bit.

Any help would be greatly appreciated.  Thanks.
