Everything was fine up until recently. Most likely after a few recent updates, the BIOS stopped recognizing 2 out of 4 of my RAM sticks showing 16GB RAM installed. However, for some weird reason, the windows task manager shows 32GB of RAM installed provided I enter BIOS before booting the system. If I simply power it up and let Win10 boot on its own, the Win task manager shows 16GB of RAM installed. This is not a hardware problem since we have correctly seated the RAM and cleaned the slots with Alcohol, interchanged the RAM sticks onto different slots, and done whatever else we could check whether the hardware was faulty or not at first. Please advice..

what you see from bios is spd readout
you could check with hwinfo to see if spd gets recognized there
if all fine there...then its just bios bug

hwinfo64 -> memory
here you should see 4 rows with stick spd info
then hwinfo64 -> motherboard -> smbios dmi -> memory devices
here will be memory devices, when u click it, it would tell what bios reads
