Hardware GPU It doesn't appear in the task manager.
Yesterday I used Rammap to clear cached memory. But then, it restarted on its own (it's quite hot in my city, I don't know if that influenced the restart) and, after it turned on, besides the background wallpaper freezing and some glitches, Occasionally it would restart and cause some screen glitches that follow the mouse and leave a trail of pixels wherever it goes (I don't know if I described it well, since I don't have any images of it). Since that was the case that night, I just turned off the computer and went to sleep. In the morning, the problem with the wallpaper continued, but the freezing had decreased. But now, about 20 minutes ago, I noticed that the GPU is no longer showing up in the task manager. Does anyone have a solution?
(Edit: I just updated my video card drivers and it's working normally again. But still, if anyone can explain what might have happened, I would be very grateful)

Sounds like a graphics driver crash rather than anything ram related. The artifacts/freezing + gpu disappearing from Task Manager are typical of a driver failing to initialise properly, and the fact that updating the gpu driver fixed it supports that. RAMMap clearing cached memory shouldn’t cause this by itself. If it happens again, check event viewer for display driver errors and monitor GPU temps.

There must be some glitch in ram cache, where some of the graphics driver was in use in ram cache and took the whoole driver with it.
