SAFE MODE: It is the heart of the maintenace people. In safe mode, All critical processed and service only get loaded during the booting process. All other likes display, sounds etc. are blocked. The main intension is to provide a smallest set of resources to be used to diagnosis the problem in windows. When windows got into a problem Then we can try running it in safe mode. On which we can restore current setting to prior versions.
HOW TO DO IT:
When we boot the computer. The first screen display information about the BIOS, 2nd screen tell information about your computer at that time, try frequentely pressing the F8 key.. you will see a windows startup menu stating Safe Mode, Boot logging, Command Prompt Only etc. Choose Safe Mode and press enter.(It should be noted that some time: many BIOS goes to boot choice menu instead of booting the windows. So when window start booting then try F8 Key.
I DON't WANT TO LOAD WINDOWS? WHAT SHOULD I DO.
Repeat the step above, and Command Prompt Only or Choose Safe Mode Command Prompt only. If you have Win98 or prior you directly get into dos prompt in others all component get loaded then the DOS prompt will appear.
ENABLE BOOT LOGGING is also the best thing to check out the log record and the faulty services.
