Hoping our iMac will get well soon

While in the middle of writing something the computer screen suddenly become one big pixelated checker board. I turned it off and on. Then it was a screen covered in stripes. Kind of like those stripes on baby blankets everyone gets for their newborns.

Then the screen went completely white. A sad lonely desolate white.

i hope the graphic card is all that needs to be replaced. I hope our auto backup was working.
