Bios time resetting to some previous year date. pls help. i have even reinstalled the system - it worked for 2days and it's back to it's previous state. when this happens the system is in an endless booting state.
The time and date not saving or resetting in the BIOS is most often a sign that you need a new CMOS battery. They're a common coin cell battery CR2032 that costs maybe $2-3US at almost any electronics store, and even several larger retail stores.
