My system is in portuguese, i'm sorry if this makes things more difficult

At the beginning of the year, I bought a new SSD (currently C:) because my old one (currently D:) had this issue where it would reach 100% disk usage from almost anything, even just being on the desktop.

After that, I spent the last few months using the C: drive as my main system drive and the D: drive only for installing games. For about two months, the D: drive worked normally, as if it had never had the 100% usage problem.

However, the issue has returned, and now it doesn't matter what game I launch—whether it's a very lightweight indie game or a demanding AAA title—the D: drive starts freezing again and reaches 100% usage.

Is there anything I can do to fix this? I don't want to move my games to the C: drive because there wouldn't be much storage space left on it.
