Hi All, I am having a problem running win XP on my HP Presario notebook. Everything was fine until I tried to scan my system for root-kits using regrun reanimator program. It asked me to restart now as it will check for those root-kits at next restart. Now the system starts up, win XP logo screen with progress bar comes up and then the next screen comes up which is supposed to be the login dialog. But, here, nothing comes up. only the mouse cursor is there that can be moved. keyboard is not active, I have to use power button to shut down. I have searched many discussion threads and used all the schemes from safemode and other startup options, to setup CD based repair of windows. But, all result into the same blank screen with a movable mouse cursor and that's all. The last thing, that comes to mind is some problem because of that reanimator software. I have used its earlier .exe versions and they did do a good, smooth job. But the latest version actually installs on the system. Another clue, may or may not be of use, is that even before trying anti-root-kit action by reanimator, I tried opening my simple text file that I used to write few comments. It didn't open up in notepad while in the process explorer, I could see the instance of notepad running. Thanks for your expert advice in advance.
