Yes, that’s right, ticking! Every game on kongregate that I have tried to play today makes a ‘tic-tic-tic-tic’ noise, It’s not my earphones or flash, non-kongregate programs work just fine.
In addition to this ticking, the screen has this odd screen effect, like the pixels can’t seem to decide where to go. Parts of the screen are ~1px to the left, part ~1px right, up or down. This makes it annoying to play anything. This is especially weird because the advertisements on this site work just fine :-(
