hello In one of my systems, The time is not taking properly, it setting to year 2000. I changed the CMOS battery still the problem persist. What couldbe the problem. Please helpme.

My first guess would be a corupted BIOS, try re-flashing the BIOS(but only if you're comfortable with performing such a procedure)

Thanks for reply I don't know how to reflash the BIOS. can you explain the procedure for BIOS re-flashing. any other suggestion or information please I am waiting for your reply. pat

Before you go down the flashing road (can be quite daunting if your not sure what your doing) try clearing the CMOS. I'm doubtful that this will work but it's worth a shot. If you do want to go a head and flash do some research first. theres loads of stuff out there about how to do this. hope this helps

The bios reads the mainboard clock. This is a quartz chip that is soldered into the mainboard. If it has gone bad you have to replace your mainboard. No bios flash is going to fix this. You should never flash a bios unless you KNOW its going to FIX YOUR PROBLEM. Flashing your bios can be the quickest road to a making your pc a boat anchor. Think about all the fools who do with without hooking up a ups? Power outage during a flash and you have nothing but trash.

You say the time,is wrong, but then use the date as an example. When your pc asks if you want to change the date (or time) it shows the format. e.g. dd/mm/yy When this occurs with the date, enter it as dd/mm/yyyy Good luck - Keep us posted.

I kmow this is going off at a tangent but wanderer a faulty BIOS chip does not mean you have to replace the board. BIOS chips can be replaced and i personally haven't come across a mobo where the BIOS chip is directly soldered to the board.
