I have a Lady Friend running xp home edition on a about a 3yr old dell .and have [BSOD] codes ?

codes are :0x00000024,0x00190203,0x86FD00F8,0xC0000102,0x00000000 .First off no hardware or software was changed or modified by user .Tried F8 It will not go back to it's Last Known Good Configuration . Have tried using a boot disc set .

System was purchased without O/S cd's through [rent-a-center] by my friend about 2yrs ago it was bought used .

comes back to Blue Screen Of Death with the error codes.no matter what I have tried so far.

I don't know how old the battery in the mother board is[I will replace that ] if that has no effect ,I was thinking of trying to see if it would accept a windows xp upgrade disc ?.

Or would it be better to just pull the hard drive and replace with a new one [havn't gotten into it that far but it is all factory parts have never been modified it has a 40gig HDD though]?

I would appreciate all the incite and assistance .

I and my Friend would appreciate your assistance and GOD BLESS YOU for all of your help everyone .
