Stripes displayed then plenty of small rectangles and never completing startup ...

What happened to my iMac 27 ? Here is the startup screen.

After a while ... never completing startup.

Tried install High Sierra from Apple but same result, never ending install.

Any idea ? Hardware issue ? Can it be repaired ?

I googled about this failure and found that this one is well known and occurs very often.

Some people created even videos on how to proceed ...

Maybe I'll try. Should I not succeed, then I'll give up and won't replace it.
