Windows Safe Mode
Windows OS switches to Windows safe mode whenever an operating system becomes unstable, which may be due to recently installed hardware driver. Windows safe mode lets you troubleshoot the operating system or undo an action that is preventing the computer from loading normally. When the problem is resolved, you start the computer in normal mode again. Safe mode does not use normal graphic device drivers, rather, it uses standard VGA mode. Sometimes, it is helpful to use safe mode to remove spyware, viruses, or other types of malicious software from the computer system. You can invoke safe mode by pressing F5 or selecting it after pressing F12 on your keyboard during the boot up sequence.
When your computer boots on safe mode, the first thing you need to do is to ask yourself, have I made any changes recently. If you installed a software driver, go back and uninstall it. If the system does not boot normally after undoing the last action and rebooting it, try undoing the second to the last action before the problem. If you undo the recent changes and your computer is still rebooting in safe mode, then you may have a corrupt registry. To resolve the problem, you would need to install a fresh copy of the operating system. Also, you may be able to use the system restore utility to restore a working point before trying to reinstall a fresh copy of Windows.
System Restore in Windows 7 and Vista Safe Mode
Open the 'start' menu and type 'system restore.' Click 'next' and choose the restore point you wish to use by highlighting it and then hit 'next'. Make sure you have saved any documents, then click 'finish'. The system will restart and revert to the settings saved in the restore point.
System Restore in Windows XP Safe Mode
After you are in safe mode and logged in as an administrator, click 'start'->'Run'. Type cmd and click ok to bring up a command prompt. At the command prompt, type %systemroot%\system32\restore\rstrui.exe, click enter, and then follow the instructions.
Some causes of a Corrupt Registry
Shared DLL and Active X control errors occur when you don't properly uninstall programs. A major problem, perhaps the single reason that contributes to a lot of corrupt registries, is that caused by malicious software. Malicious software often comes with free downloads. When installing these downloads on the computer, the embedded malicious software creates dubious entries in the registry or links to some important files. These are not the only things that corrupt the registry. Wrongfully editing your registry can also lead to a corrupt registry. To prevent registry problems from damaging the entire registry, the best thing to do is to get a good registry cleaner. Manually editing your windows registry, if you are not a techie, is not a good idea. Also, if you do decide to edit your registry, make sure you perform a registry backup before making any changes.
