I ran a program that replaced important system files (of course I was not planning for that to happen) so when I boot up my computer I get the following error message.
When the welcome screen should come up:
stop: c000021a {fatal system errors}
The Windows Logon Process system process terminated unexpectedly with a status of 0x80000004 (0x0000000000 0x0000000000).
The system has been shut down.
This is strictly a software problem.
I am running Windows XP Pro.
I really don't want to have to do a clean install. I'm on the same computer now but with a different hard drive but I can access files on the other one.
Any help would be appreciated.
