1. Your post has few details. Just the crash and the popups. But if the machine can't be booted at all isn't entirely clear. I can't tell if there is a heat issue (pretty common on old machines that run XP) or if we can use Grif's advice.

There are some words shown when you post. Well maybe not. Here they are in case your machine doesn't show them -> Note: If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem. Also please exercise your best judgment when posting in the forums--revealing personal information such as your e-mail address, telephone number, and address is not recommended.
-hello = my main computer which runs XP came up with the BSOD saying "STOP c0000 21a (Faatal System Error). The session Manager Initialization System process terminated unexpectedly with a status of 0xc000003a. The system has been shut down". I was removing some recent security updates, because IE8 has been plagued with recurring popups of Search and I had to uninstall SP3 so
that I could remove IE8 (and then reinstall both).I tried every
method I know to restart the system including Safe Mode and reverting to when the system worked (also from Safe Mode). But it keeps shutting itself down, right after showing the Windows starting screen. Any idea what can be done? Thanks - Amos
