    Seems every time after power down and on again the next day, the system time and/or date are wrong. Noticed it first when K aspersky software complained about being out of date right after updating.
    This doesn’t seem to happen as long as the machine is left on. What could cause that? The machine is only a few months old.
    Windows 7 Home Premium, SP1, 64-bit
    Intel Core i3-2100 CPU, 3.1GHz, RAM 8G

    Can the machine read the CMOS data and boot if the battery is dead?

    Just today, Monday 5-28, for the first time I'm aware of, the system time showed a Sunday 5-27 time. But the machine was running the whole night, not even restarted. So the wrong system time can't have been due to a weak CMOS battery. There must be another reason.

    Just to make sure..When you changed CMOS battery you reset time, date, and time zone in the BIOS menu?

    It can also be malware .. So what have you done so far to resolve the issue?
