Recently my computer has had an issue involving strange high RAM usage. Right after starting up, the RAM usage is kind of high (about 48-50% of 16GB) but it's still usable. After I open some apps for working, it grows to about 80-85% and at this level, it's still usable. Usually as before (about 1 month ago), it's always stable at this level even after leaving the computer run for several days (even several weeks).
But after the issue arose, it now can grow fairly quickly (about after 1-2 days left running) to 96-98% and at this level I can't use my computer normally (it's always sluggish and unresponsive). As before I set the max memory for WSL (I use Docker Desktop) at 4GB and now tried reducing it to 1GB but still the issue remains.
By looking into the Task Manager, I think it's definitely some kind of strange issue (all the visible processes' RAM usage cannot add up to such a high total RAM usage).
It's even more obvious when looking at the Users tab of Task Manager, the total RAM usage for that only user is just about 3.6 GB but occupies up to 98% total RAM (of 16GB)? That's really strange.
I've thought of a memory leak issue caused by some app/service but don't know how to track it down. But as I said before, it's already strange right after starting the computer (when the memory leak issue cannot be the case), the initial memory usage is still fairly high (48-50% of 16GB). This computer is my office computer, I have my own laptop installed with only 12 GB of RAM (using the same Windows 10 with latest updates installed) and the init RAM is just about 25-30%. Of course the startup apps/services on both systems are different.
I've used Windows 10 for years since it was released the first time but this is the first time I've encountered such a strange issue with RAM.
Can it be any issue with hardware (the physical RAM device)? Could you help me diagnose this kind of issue, currently I may have to turn off the computer at the end of the working day (as before I left it run for even several weeks without any issue).
