Display video & audio "lagging"

I built my own PC about 5 months ago and I've been noticing this problem ever since, it happens about 3 times a day if I'm using it all day, but sometimes not at all. This doesn't happen at specific times, that I've noticed.

The audio and the video coming from my PC with a HDMI cable (I've tried several) randomly starts to lag, if I move the mouse it moves jerky across the screen, along with everything on the screen playing jerky. The audio sounds like some sort of 8-bit music when this happens, too.

I have a NVIDIA GTX 670, with the latest drivers, I've even installed GeForce Experience to try to see if that helped, however it's continued to do this.

I'm just looking for any sort of help or advice with this, it's not a really bad problem but obviously I want my computer to be running smoothly. As mentioned, I've tried several HDMI cables, and some different settings on the monitor.

Boot disk is a 320GB SSD
ASUS Sabertooth Z77 Mobo
Intel Core i73770K 3.50GHz @ 3.5 GHz
16GB System RAM
NVIDIA GeForce GTX 670

And temperatures are running fine, plenty of cooling.
 
Hmm, it could be anything, such as your PSU, or the MB, or GPU, or a corrupted OS. So first try a Dual link DVI cable instead of HDMI. Then if you can manage a spare GPU and PSU try it.

Try to format and clean install of OS. Update windows, Java and Flash.

What is the make /model of PSU ?

I really want to refrain from having to perform a clean install of Windows, as there's a lot of programs I'd need to re-download. I'll leave that as a last resort.

Everything on my PC is up to date, and the PSU is an OCZ 750W ZT Series Fully-Modular Power Supply.

Edit: My PC has probably been on for 10 hours now, and it seems to be happening more frequently. The temperatures are still fine, too.
 
Did you tried with DVI cable ? I think the problem lies in hardware, to be more specific the MB. You can try with a different keyboard and mouse. Before buying any components try to clean install the OS, I know the hassle, but still you have to do it.

I've ordered a DVI cable and it should be getting here sometime this week.

I might reinstall things now, and see how it goes, if not everything is in warranty, the hard part will be finding out where the problem is though.
 
Just wait for the DVI cable to come. After its arrival start from scratch with the cable plugged in. As I said earlier it could be anything like PSU, MB, or GPU, again I am saying try to borrow the components from someone to test, specially PSU, GPU, ofcourse if you could.
