To hit on the cooling subject again, it looks like the iMac's heat could be causing the screens to turn yellow, adding to the problems of flickering and blacking out screens. I think there is going to be a quiet recall. There's lots of video on YouTube now of the problems.
Let’s see if I have this about right. You ordered a bunch of parts and a case. You got some tools and took some time installing everything and plugging it together. Then you installed Windows, installed all the drivers, and checked that everything is working as expected.
Then you installed AV, etc., until it was at a base level you liked. You got it on the network, downloaded and installed the updates.
Then you rebooted and played with the timings until you got your desired overclock, went into Windows and made sure everything was still stable.
Do I have that somewhat right?
After I got my iMac out of the box, I plugged in the power cable, plugged the keyboard into the iMac, plugged the mouse into the keyboard. I turned it on, put in my username and password. My wireless doesn’t broadcast SSID or do DHCP, so I went to the network preferences, typed in the SSID and a password, gave it an IP and I was online (notice nothing about selecting encryption standard or MTU, that was automatic). It would have been “Pick a network and type a password” if I broadcast SSID and used DHCP.
It was less than five minutes between it being out of the box and me happily using my computer.
Now do you see the difference?
I have also flawlessly done an in-place upgrade of the OS twice since then. You never do that with Windows.
