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
