iMac black screen issue
So I purchased a 2010 Mac with a fried PSU it was black screening seconds after the boot logo came up. So now I replaced it with a new PSU and the black screening issue still happens but it takes longer to happen. I can use it for an hour or two but certain tasks make it wanna black screen but sometimes it doesn’t. Any help?
Let's run the onboard diagnostics. Restart your system press the D key. Let us know what happens and the error message/s
