Is the GPU dying?
A few months ago, my iMac suddenly shut down, and wouldn't turn back on. After getting it checked and serviced, I was told that the Logic Board(?) was dying. However the Mac still can boot, although the screen wouldn't turn on unless I manually restart the Mac around 2-4 times.
According to a forum, it's caused by a failing GPU. Apparently it can be "fixed" by basically reflowing the solder. I don't want to take the risk of damaging the card by heating it up, however, so I wanted to know. Is this actually caused by the GPU?
If it's the GPU that is failing, I have plans replacing it with a newer Radeon 6xxx card.
Ist dies eine gute Frage?
