The OS used in my PC is Windows XP Professional SP3, duly updated. Suddenly (starting some days back) the booting process has become extremely slow. It takes 5 to 7 minutes for the PC to become operative, before I can open anything. I have checked BIOS settings and reset these as recommended. It is extremely annoying.
The total booting time used to be 30 to 45 seconds. How can I restore the PC to to the normal (fast) booting mode?
