Here's a link to the video.
I don't know why this happens every now and then. One minute it's in good shape, then it just jumps like this. It's very irritating and it gives me a headache. I don't really know what I'm doing wrong, I've used CCleaner, ran the antivirus, restarted it and all and it still does this.
I'm on Windows 7 and I'm using an HP Pavilion. Any advice would be greatly appreciated!
