Monitors keep shutting off

Question

I have a Mac Core 8 with two 23" monitors that I bought about a year ago.
For the last few months, both monitors will suddenly go black for no apparent reason.
The computer isn't going to sleep as the applications are still running and the hard drive still begin accessed.
(for instance, if I'm running music software, the music keeps playing) and the power lights on both monitors stay lit up.
Once the monitors go black the only way to get them working again is to power off the computer using the power button, and then restart it again several times.
Usually the process takes about 3 to 5 restarts.
The first time I restart, I get the startup chime but the monitors stay black.
The second time, maybe just the left monitor will come on.
Then on the next attempt, only the right monitor will come on.
On the final attempt, the right monitor will come on by itself, and then about 10 minutes later, the left monitor will come on as well and I can finally use the computer again.
I can't shut the computer down or I end up having to go through this whole process again.
So… any ideas on what the heck is causing this?

Answer 1

Quit/close all apps completely and restart the iPad. If this helps, make note of the app that you last launched if the iPad crashes again and assume that app is the culprit causing the crashes.
Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
You can also try rebooting the iPad and see if that helps. Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
