Wrong Time And Date when computer shuts down

[Rick Moore]

Every time I shut down my computer it starts to load and gives two beeps. then it says incorrect time and date.
it does NOT do it when I restart my computer, Only on a total shutdown and restart.
so, I boot it up and change time/date to current and it is fine as long as I don't shut the computer down completely.
I changed the battery, tested memory, hard drive and CPU. all are ok
within the last couple weeks it has started rebooting by its self, just goes black and reboots/restarts.
when it boots back to windows I get the "windows has recovered from a unexpected shutdown" there are No issues in device manager

today, I took everything out of the case and cleaned the dust, new cpu compound and 3 new fans.

could this be a mother board issue? I reset the motherboard/bios already
could it be a CPU issue? temps are 29C
could it be a memory issue? memory is reading correctly
could it be a power supply issue? it seems fine

thank You all for your help.
rick.

Check that you've inserted the CMOS battery with it's positive (+) side (the flat side) facing up.
If it's the wrong way up it's effectively the same as having no battery in there at all.

How old is the M/B? Repeated hot-cold conditions (power on/off) will (eventually) crack the circuits on the M/B. Most circuit boards will fail this way in the end.
