Weird display issue - graphics card?
A relative shipped me a "dead" iMac (2009; 21.5"), saying that they thought it would be too expensive to repair the "motherboard". (They got a new Mac instead.)
However, when the iMac arrived, I plugged it in and booted it up in order to make my own diagnosis. Here's what I got:
The mouse moves, and while the boot up seems mostly clean up until the end, at the last moment, I get only a partial "image" with some old-style static/pixelization at the bottom.
Following the tips & tricks here on this board, I plugged in an external display to confirm the source of the problem. No surprise - the external display is also static-y/pixelized.
From what I've read here so far, I am 90% certain this points to a fault in the graphics card itself.
Can anyone else kindly confirm this?
