Hi everyone, a month ago I sold my GTX 580 and I recently bought a GTX 780.
With the new card, I finally installed Mavericks in my system too.
Everything works except sleep.
The first time I can put my PC in sleep (with 20-30 secs of delay!), then, if I want to re-put it in sleep I can't. The monitor just become blank for 3 seconds and then it returns normal.
In Mountain Lion I haven't got any issues and there isn't delay while putting the PC in sleep.
What could it be?
Thanks in advance!
