    I was installing software for a new piece of audio equipment when the installation started taking forever. It said "about one minute remaining" on the installation but that took nearly 15 minutes. After the installation there was a mandatory restart. Upon restart my monitor did not come back on. I did a force shut down and tried again. Same thing. I tried this over and over but no luck. I then switched over to a different video card. It is a GEforce GTR 580. I hooked it up via VGA to DVI adapter. IT WORKED! Well, so I thought. My monitors came on and I began just using the computer as I normally do...but EVERYTHING was running extremely slowly. Every action required a long pinwheel wait. I ejected the installation disc from the previously mentioned software and decided to just properly restart the computer. And of monitors decided to not come on again. Now I started trying everything. Different VGA cables, different power supplies, different monitors! AND decided to work. Strangely enough, it worked with the original configuration. Old video card, old monitor. I can not explain why.

    Well, I woke up this morning and tried to turn the computer on. Surprise, surprise...the monitors are not turning on. Sometimes the keyboard still works (as i can engage the capslock key to indicate it's working) and other times it's not. I am just wishing someone might have some insight on it.

    It's a 2009 2x2.8gHz Mac Pro with 16gig of ram. A couple internal HD's and an external 9gig Raid. Running OS X Lion.

    Is the console log full of errors, that is if you can see them?

    I'm still fiddling with it to get the monitors to work again. Where can I locate the error log?
