Solve : Monitor Display Keeps Going Black?

Answer» Hi; I have just finished a new build which for a week was working fine the all of a sudden the monitor keeps going black. The only changes that took place around the time of the problem were installation of windows updates which included Service Pack 1 and the other possible culprit was trying to install Adobe Flash Player 11 which I needed to watch video demos of games in Steam, Adobe downloaded and installed but Steam Videos still didn't work. I had also swapped the CPU which is an AMD A6 5400K which has a built in APU, although I'm sure that the display worked after this, in fact i'm sure it did. The problem is I cannot pin down what caused the problem.

Hi;

I have just finished a new build which for a week was working fine the all of a sudden the monitor keeps going black.

The only changes that took place around the time of the problem were installation of windows updates which included Service Pack 1 and the other possible culprit was trying to install Adobe Flash Player 11 which I needed to watch video demos of games in Steam, Adobe downloaded and installed but Steam Videos still didn't work.

I had also swapped the CPU which is an AMD A6 5400K which has a built in APU, although I'm sure that the display worked after this, in fact i'm sure it did.

The problem is I cannot pin down what caused the problem.

Not tried another monitor yet but will do today I have a couple of displays with VGA inputs.
