I was having heavy problems with my system since the day I upgraded my machine . It used to auto reboot or give the exception 0E error. So I decided to use Norton disk doctor. And you wont belive me it showed me more than 100 error on my machine.
Some features of this software are
1.Norton WinDoctor : diagnoses and solves Windows problems.It repaired errors in my machines registry , COM dll errors.
2.Norton SpeedDisk : optimizes the disk by putting your common files near for faster access.It defragmented my disk which windows could not do.
3.Norton Disk Doctor : is used to detect hard drive problems.Repaired free space error on my machine.
4.Norton System Doctor : finds disk and system problems but can automatically prevent a minor problem from turning into serious trouble. It did not work on my machine some files were missing.
Now I do not have any problems in my system, Thanks to Norton.
