Hi,

For the last few days, the system time displayed on the right hand corner of the task bar of my desktop PC is incorrect, typically 7-8 hours slow. I change it first thing in the morning when I switch on the PC and it works fine for the entire day. But when I switch on the PC the next morning, the time displayed is slow by 7-8 hours. The system date displayed is correct though. And there is, otherwise, no problem or issue with the PC.

Can someone tell me the cause of this problem and how to resolve it?

My system configuration is as under:

AMD Athlon II X3 440 Processor on MSI 880GMA-E45 motherboard with 2X2 GB Kingston DDR3 RAM

OS is Windows 7 Ultimate 32bit.

Thanks!

there is a battery on the motherboard, it is dead/dying. change that. looks like a silver button (garment button) cr2032 lithium.
that powers the real time clock in the BIOS. windows is getting it's date and time info from the BIOS, which is a clock running slow/not running.
turn off the pc, open the case, find the button cell,pop out the battery, pop in the new one, go into the BIOS and change the time date settings.

Hi vanderluzt :)

You may have to clear and reset your CMOS, then go into Bios and set your time and date.
Try this first.

Three things usually cause this issue.
1. CMOS battery failing
2. Time Zone
3. Malware.

First off, thanks for the response!

You advised me to clear and reset the CMOS and then change the time in BIOS. If I understand correctly, this entails entering the Setup and loading default BIOS values, then change the time, and restart the system. However, changing the BIOS values might overwrite any past changes made to the BIOS. So is this advisable since I don't really remember the BIOS changes [if any] that I might have made? I have been using this system since September 2010. Another member here suggested replacing the CMOS battery. So which do I try first? And how long does a CMOS battery typically last?

if you are concerned about the settings in the BIOS. go into BIOS and write down what each setting is. bummer. after the reset/battery swap you can reset the settings.
batteries will last 4-5 years. depends on the cell.
I jumped to the battery being the fault due simply to the age of the motherboard, about as old as min, and I have changed my battery twice.

I replaced the old CR 2032 battery with a new one last night, started the system, then changed the date/time by entering Setup. However, I did not tinker with any of the other BIOS settings. It's showing the correct time since then. So hopefully, the problem is resolved.

Thanks!
