CTRl Alt Del Login screen not showing

[Guhanath]

Few days back my PC infected with virus and trojans.Bit Defender identified
it and deleted few files but after that safe mode didnt boot up(culprit from
my understanding is rundll.exe in c:\windows\system32\rundll.exe).

it shows the black screen with "safe mode" letter in each corner of the
screen but ctrl alt del login screen will not show up. The normal boot was
working fine till today.From this evening it also shows the same problem, so
i could not log into windows at all. how can i rectify this problem.

i dont want to reinstall OS again as I have installed many applications.

Is there any way to
1. To identify what is going in the background while it is booting?
2. system restore from cmd prompt(recovery console)?
3.change the ctrl alt del login screen to normal xp login screen without
logging into windows?
4. Is there any connection between ctrl+alt+del login with rundll exe?

PC config is:
WinXP SP3(RC),Bit Defender 2008, AVG 8.0,
My System is now free from virus and spywares

It's probably the easiest option and the only one easily given to you
without being able to see your machine.

Being that you have SP3 - you should create an SP3 integrated installation
CD to utilize to perform the repair installation. Know that a repair
installation is usually non-destructive. However - whenver performing
something this large - it is always better to back up everything you can
(either through a BartPE boot CD or an imaging utility to backup the entire
disk 'as is' - those seem the easiest/most complete methods given your
situation.)

Also - I wouldn't be so sure your system is spyware/adware or virus/trojan
free - since it doesn't boot completely - how could you be? *grin* (You
might even have a hardware issue!)

You cannot do much from Recovery Console. You need to replace system files.
The 'Repair' option offered during a setup, right after the EULA agreement
screen, will probably restore the old registry and system files.
