Where can you go to have the Dell Computer error messages explained?

 

Could I get an explanation of the following error code:

IRQL_NOT_LESS_OR_EQUAL

Stop: 0x0000000A(0xFFFFFFE8, ox00000002, 0x00000001, 0x80522985)

 

My computer (Inspiron 6000 with Windows XP) does not boot in any mode including the SAFE mode.

 

Is this a hardware or software problem?
