Do you have your location & time zone set correctly as this controls the clock timing.
If it's only the time that is getting out by a few minutes then check your time zone, but if the date is being lost as well then it is most likely the CMOS battery.
Yes i have location and time zone set correctly.i checked it.the difference is not in minutes but in hours.Also date
is changing as well.Its not CMOS problem.Because previously it was ok.I think i `ve got a nasty virus.
The time & date are stored on the motherboard, not in the Windows Operating System, so a virus is unlikely, but a flat or failing CMOS battery is very likely.
The question is why it worked previously.But now its not working.If it was CMOS problem,it should have shown wrong date and time from the beginning.
From the begging of what?.The question is why it worked previously.But now its not working.If it was CMOS problem,it should have shown wrong date and time from the beginning.
oh!
this is important point.
Now i suspect CMOS error.
i will try to repair it by opening my laptop.
But if there is any other method,then please do let me know.
by the way i use combofix about an hour ago to remove any hidden threats.it gave me a BSOD Error.
A search on the internet revealed the following about Combofix.
Do not use ComboFix on your own without supervision. - Microsoft Community
ComboFix usage, Questions, Help? - Look here - Anti-Virus, Anti-Malware, and Privacy Software
So you may have created a problem. Can you start the computer in Safe mode & perhaps you can find the problem in safe mode or uninstall Combofix.
The CMOS battery is located on the motherboard, so you may have to remove the to reveal it. They are usually a 2032 3 volt lithium button cell & clips into a slot on the MB & it looks like this.
