Monitor flickers off and on again occasionally

Right, I don't know what this is and it only just started happening after having this display, graphics card and computer in general for over a year.

I haven't made any hardware modifications recently that could've affected this.


Now, the problem:

Every now and again, my monitor just goes to black (as if it's receiving no input) and then 2 seconds later comes back on. This only happens every 1 / 1 and a half hours - but it's still a little irritating.

Anyone know what the problem could be? I've already checked if it it's a loose connection or bad wire and it's neither of those things. Apart from this issue my monitor works perfectly.


Thanks a lot guys.
