Monitor flickers off and on again occasionally


Aug 5, 2010
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.
It may just be the UAC bug. Try this:

If not, please supply a full list of hardware.
