I have the same blue screen error that happened today on Compaq Presario P4,
My daughter ran some updates (I don't know which onesw) and now nothing
works. My computer is running win xp pro sp3, not oem (originally came with
xp home). The computer was working fine till about 3 weeks ago it started
crashing, thought we had a virus so updated virus software to Norton and now
today the system crashed and we are getting error message "Stop:c000021a The
session manager initialization process terminated unexpectedly with a status
of 0xc000026c". Is there a way to recover or do I vae to wipe the harddrive?
