My system (TC A55) deveolped some problem in booting. Every time the POST error showed that
"ERROR 0162:CONFIGURATION CAHNGE HAS OCCURED. DEFAULT CONFIGURATION USED".
Some times, even it boots without any error the Win XP , after booting, reports that " ONE OF THE FILE CONTAINING THE SYSTEM'S DATA HAD TO BE RECOVERED BY USE OF A LOG OR ALTERNATE COPAY. THE RECOVERY WAS SUCCESSFUL".
Now it is even get worsen. Blue Screen of Death (BSOD) appears often and Windows get crashed frequently.
