I have been having intermittent HDMI signal loss and it is beginning to get worse. Does someone know how to find out what's causing the problem [computer: hardware or software, monitor, or HDMI cable] ?

I have a desktop computer (HP Pavilion with Nvidia Geforce 530) with an HD monitor (iiyama XB2374HDS), both relatively new (Christmas or so).
I have been having intermittent HDMI signal loss and it is beginning to get worse. At first I thought it was a problem with energy settings on my computer or graphics card, as the monitor wouldn't get any signal after getting back from sleep mode, or after being turned off because I hadn't used the computer for a while.
But now it sometimes loses the signal anytime, when I'm typing, and even rebooting the computer doesn't always do the trick.
Sometimes, but not always, moving the cables around gets the image back.
Does someone know how to find out what's causing the problem ? Is it:
* hardware problem with the motherboard or graphics card or something ?
* drivers problem ?
* monitor ?
* hdmi cable ?
I don't have another cable on hand to try, and as it doesn't always happen anyway I wouldn't be sure of anything (unless the problem occurs which would tell me it isn't the cable).
