Blinking

[VARN]

My screen is blinking on and off, it used to do it every couple of hours; now it is happening every few seconds, plus it has red dots in a few places. How can I tell if it is the grapfics card or the monitor?

 

It has taken me almost 30 min to post this because the screen went black; it was still receiving a signal though. It has gone back to blinking now.

 

Seems to blink faster when I move a window around the screen, and the red dots are only on the desktop (they should not be there).

Are all the wires plugged in like they should?

 

Do you have another monitor that you can try this on?

Seems like a loose plug or a graphics card problem. What are your system specs? Although, the red dots would be stuck pixels, so it could also be a monitor problem.

Everything seems to be back to normal now, Could this be caused by leaving the computer on too long? I have changed the power settings to not turn off the computer or monitor.

I'm thinking this was just a loose plug, but I can't be sure. An 8800 is still a strong card, so I doubt it's a lack of resources.
