I will give it a try later. I have a different brand card. We can compare results.
No problems with the update. I am going to have to re-enable sounds but the computer started right back up.
The only thing I did differently is that I changed my computer from 5.3 to 5,1. I will report back when I have everything going.
I don't know what else to do. I started from scratch, erased my sdd and installed 10.8.3 using Unibeast. Everything went fine, then I installed the GTX 660ti again and got the same error. Looks like this build does not like my card :
So sorry. Is the Graphics in the off position? (I forgot what we had to do in Multi at startup.) Check all the settings again.
Put your BIOS at a slower speed? Slow down the Ram and processor to see if you can get it running?
I tried sleep again. (USB 3.0) This time my music kept playing but the screen did not come back on.
I am going to try sleep again. USB 2.0
