CMOS settings wrong

[karan4]

What are the possible reasons for cmos settings being wrong ??

a dead battery most probably.

A wet motherboard.

Seriously, it happened to me.

I have changed the battery but still in my computer the problem is not resolved.....and I don't know how to dry a motherboard ???
It is very frustrating every time I boot my pc i have to configure the bios date, time & boot device priority
from some sources i came to know this ----

A virus that's changing the CMOS settings, may also be the cause. Do a thorough check-up with an antivirus. For the frequent SMPS damage, check the input AC Voltage and the earthing of your electricity distribution.

I have used many antivirus ...but it didn't help
I can't understand what is SMPS

check ur jumper settings...may be it is in "Reset CMOS mode". ......just guessing....

^^ Yeah thats right, you might have either taken the jumper off(or it fell off) or you might have put it in the reset mode. Refer your motherboard manual to find the CMOS reset jumper. It can also be called an ESCD jumper, so look for that if you dont find it.

ESCD = Extended System Configuration Data
