My monitor sometimes goes black. Like if I walk away it will act like its in standby or something and will be on with no signal. But there is no getting it back on. If I turn it on then off it gets signal because it doesnt turn off but it stays black, even though you can tell its on. I just built this system so I'm not sure whats up. It runs fine when I don't encounter this problem, and it doesn't do it unless I am gone for a while.
Also I think it might have to do with monitor because sometimes I have to restart twice because the first time it doesn't pick up signal.
