A few days ago while working on the internet, by mistake my brother tried to syncronise the time with internet time server from date and time properties. since then the time and date settings have become unstable. every time i log on to the windows, the system time reduces by 10 to 20 minutes. if i dont work on the computer for quite sometime, on booting a message appears telling ur bios settings are incorrect. press f1 to change settings. the time settings in bios changes to 00:00:00, 2001. i tried to change the setting but it didnt work. i use win xp and win 98 as dual boot. i cant figure out whats the problem. pls help me
