[SOLVED] Acer Nitro 5 ram/performance issues after installing second m2 (SOLVED)

[jaudausau]

I've run out of ideas here, so I hope someone have any ideas. A while ago, I bought and installed a Kingston 1 TB m2 as a second drive in my Acer Nitro 5 laptop. Right after that, it started behaving strange. It's "running out of ram" by eg opening one instance of photoshop and visual studio code. And the temperature is running high just by starting windows. I therefor removed the drive, with no avail. It still acts like a 90s laptop.

Also, in task manager, it can say 90% usage, while the total of usage is barely 5gig ram. I have 16 gig installed, and it also says 16 gig in the system information. Right now, the computer is pretty useless.

Any ideas what can have happened, or what I can test to fix it?

Edit: Added system information as image, and available space on my c: is about 50gb out of 500gb.

available ram is 8gb.

Hm, well, so installed is 16 and available is only 8. Regardless of what task manager says, I thought this "available physical memory" in system info was counting the available for use in that moment, so that in my situation 8 was already in use by processes, and 8 free. Guess I was wrong then, and that it tells how much ram that is available for the pc to use in total, and not free ram. (Shouldn't "installed physical memory" speak for itself for total available ram?)

Does this indicate that something's wrong with one of the ram chips, or are there any things that could be checked in bios or in Windows?

Looked in the bios, but that bios had the most minimalistic bios settings I have ever seen.

sound like it. double check in resource monitor

and reseat the ram

Seems like my pagefile was disabled. Enabled it, and now I can open both chrome, photoshop and illustrator at once. Even Unity. Didn't think that made such an impact, like eating all RAM on a freshly rebooted windows.

And I learnt that there is something called Standby RAM, which reserve a lot of the total RAM.

Also from what I can see here, "Available physical memory" seems to reflect Standby + Free, and not how much of the RAM that is successfully installed, kind of. As per the Resource Monitor, my Nitro is actually using almost 14gb ram now, and it runs pretty smoothly with the mentioned programs running.

I might just upgrade to 32GB RAM, to increase my overhead for RAM usage. But I will mark this as solved for now, as enabling pagefile seemed to fix the worst of it.
