The cooler cracks very strongly and raspberry ripples on the screen even before loading the BIOS and when loading the OS, what could it be?

Question

Video cards

1. The cooler is clinging to something, and therefore a loud incessant crack is heard. Either the cooler is offset along the axis, or there is dust / screw / something else.
But they cleaned the dust, there is not enough of it to clog our cooler.

2. Long loading, which in this case indicates:
"System garbage" and poor performance.

3. Ripples on the screen: maybe it's a video card, it's not clear yet. It is likely that the contacts are on the video card.
Here is an image with the operating system loaded:

And when the computer starts, black-crimson rectangles and a black-crimson screen.

Points 1 and 3 are very disturbing.

I don’t understand why the cooler is buzzing
I don’t understand why it slows down
I don’t understand why it ripples on the display

Perhaps the whole point is in a crookedly installed Windows and a (possibly) broken cooler.

What could be the reason, who knows?

Answer 1

If the cable is vga, then this is it, or the connector. The dump doesn't look like that, I've seen enough of them in my life. Replacement fan

Answer 2

I don't understand why the cooler is buzzing

Replace it, just make sure before that that it is he who makes noise (stop it with your finger).

I don't understand why it slows down

Due to a broken cooler, the piece of iron heats up and starts throttling (dropping frequencies).

I don’t understand why it ripples on the display

Try to insert another video card. If everything is ok, then change it. If not, then change the monitor or cable to it.
