bluescreen of death

[cjy290]

ok last night i installed the windows service pack 3 update cuz my
computer was insisting on it.
I installed it, restarted it, then everytime i log on , and the
farthest ive gotten is a white box loading in the place of the start
menu, and it bluescreens with this message exactly

stop: c000021a {fatal system error}
the windows logon process system process terminated unexpectedly with
a status
of 0xc0000005 (0x00000000 0x00000000)
the system has been shutdown
