Blue screen winsrv not found

Hi. i use a dell pc with win xp home edition sp1, i started to download the
sp3 and appears a blue screen when reeboot the machine.
1st start the win boot screen, then reeboot again and again, i lefted for 2
hours to see if the problem correct automaticly and nothing happend.
2nd time i turned off the machine, when i turned on after the boot screen
appears the blue screen with:
stop:c0000135 {unable to locate components} this application has failed to
start because winsrv was not found, re-installing the application may fix
this problem.
the problem is that i cant start windows, every time that i turned on this
blue screen appears at the beggining, PLEASE ANY SUGGESTIONS. Thanks
