RAM usage problem - battery , hardware or software?

[Mihail Anghelici]

I'm not sure if i'm in the right section, anyways, i have this laptop from 2009 . The battery wear level is around 37%, so it is not quite efficient, it has degraded over the past years obviously.

So i have this 100% RAM problem. When i startup and get to desktop, from 50% the ram goes to 100% idle , and the cpu can barely process anything , screen keeps freezing. Then the memory usage would go back to 50 after a while... then back to 100 it's horrible.

My question is , could it be the battery causing this ?Because when the 100% ram happens, the fans are going crazy , and the laptop runs very hot . Could a low wear level of the battery cause such thing ?
Like , yes, i will replace the battery soon or later because its critical level but i was wondering , could it be a software problem or a hardware one..?

I'm not sure if this is the right forum for such question but i'm getting pretty desperate , 100% ram usage problem can be caused by so many things...
edit: no there's nothing suspicious under performance tab , literally 0/1 mb available (free)

You sure the ram is not just cached ?, check task manager and resource monitor to find whats taking all the memory.

How much ram this laptop have ?
What OS is it using ?

Could be possible the system is infected with a virus \ malware which best case is to reinstall the OS as it's the best way to make sure.

And no i don't believe it's the battery.

Could try downloading Malwarebytes see if that picks up any thing, but if it does better safe than sorry and plan to reinstall the OS which in turn you will want to backup any files you want to keep just make sure you scan the files first just in case.
