Hi, SO my iMac has had many cooling problems,

And it eventually couldn’t handle it,

Does this look like a failed GPU or a defective display?

If you wait longer you are greeted by a a black and white pattern (Looks like a retro game)

Can't tell from the pic alone, you connect an external display to find out.
