Second SSD says 100% usage

[Balzak]

Hello, a friend of mine referred me to this forum after I complained to him about a PC problem that I've been having. My technical knowledge isn't the best, but I'm going to explain what's up as best I can, any help would be appreciated. I bought a laptop about two years ago, at the time it had a single 16GB stick of RAM and a 512GB NVME.2. After a couple of months I installed an old HHD and it worked without any issues. Then I installed another 16GB RAM stick. In retrospect I think it was then when the 100% disc usage on the second HDD started. I assumed that the drive was old and finally broke, so I removed it and installed a Kingston 1TB SSD, but I get the same problem with that drive. It works fine for a while, then the usage ramps up to 100% and stays there until the whole laptop becomes unresponsively slow. It's infuriating. It doesn't matter if I'm using it for dropbox or installing a game, the same thing happens. I watched probably a dozen YouTube fixes for 100% disc usage, but to no avail. What could the problem be?

when in task manager, what process is using the disk? that could help to narrow it down

Here are some screenshots that I took. The computer was working fine, then read your message. To initiate the 100% disc problem, I installed Metro Exodus from to the D: drive, like clockwork, disc usage ramped up to 100%, took some screenshots and then had to restart the laptop because it slowed to a crawl
