Well let’s see. At first I got a virus then ran a virus scan, apparently I
hit the delete all button instead of repair all. so it ended up deleting the
logon file for my computer and now it can’t get past the message even when I
put in the XP disc, maybe I’m doing it wrong.

The message says
Stop: c000021a {fatal system error}
The windows logon process system process terminated unexpectedly with a
status of 0X0000034 (0X00000000 0X00000000)
The System has been shut down

ps i have a standard dell 9100
