total crash help holy stuff help help

the last thing i remember doing was installing the latest microsoft update, i may have done other things before restarting, i'm not sure if they are pertanent yet, but the bottom line is that i get the blue screen of ###### doom whenever i try to start my computer. i've tried running all the safe modes and the "last working configureation" in the windown startup menu and i can't get anything. it starts to load windows but when it seems to get to the point where it would normally give me the screen to choose the user and log in i get the death gaze: STOP: c000021a {Fatal System Error} The windows logon process system process terminated unexpectedly with a status of 0xc0000135 {0x00000000 0x00000000}. the system as been shut down. after i get that message it just sits there drooling. i'm in college working on projects and this really cannot happen now, what should i do!? thanks so much for your time and prompt responses, Jess

Hi,
Sorry to hear the problem,
This is pretty serious stuff, when faced with this problem it is often quicker and simpler to reinstall windows than to try individual remedies. Here's a link to the Microsoft instructions on how to proceed:

Note
I would print out these instructions before commencing and sign off each step to ensure that you do things correctly and observe the warning given.

If you wanted to try an individual solution then booting from your Windows XP installation disc, enter the Recovery Console and run chkdsk /r and see if this does the trick. (takes a couple of hours or so to run)
Note for each of the above methods you will need your Windows XP installation disc
(A manufacturer's "Recovery Disc" is NOT used for this procedure.)
Good luck
Regards
