Check the cable connections are tight; remove and re-insert if that makes no difference, try a replacement cable/converter.

To me it looks like "noise", interference affecting the data being transmitted, so the monitor is misinterpreting it.

It can also be a symptom of RAM damage, but I would expect the blocks to be fewer, and in all parts of the screen.

Well i just got a new computer brand new with Ryzen 3 2200g 8gb ram etc etc so i don't think the RAM is problem the adapter is brand new too i had to get it becose i have only VGA connector to Vega 8.
I did try to unplug the cables but the problem stays same even when i play a video the lines dots are moving...

Could be issue with DVI->VGA adapter.
Does your monitor have any other video inputs than VGA ?

Connect pc to monitor with DVI-D cable (without any adapters in the middle).

yeah i would do that but i have in my MOBA only DVI input.

So? What's the problem?
Motherboard has DVI-D output, monitor has DVI-D input. Connect them with DVI-D cable.

It's great, you sorted it out.

But using digital connection instead of using DVI-VGA converter would still be beneficial.
You have there digital video signal source, it gets converted to analog, and then again converted to digital for LCD. All those conversions degrade image to some degree. Possible problems are - color bleeding to neighboring pixels and shimmering effect.
With digital signal cable all those problems get eliminated.
