Solved Video Graphics on WMP 12

The video graphics has gone a little bit strange just after an hour since the computer has been rebooted. I had to reboot the computer if this happens (as shown on the picture below). This is only affecting Windows Media Player only, it's not happening on my screen; like my desktop.

I have updated my Graphics Hardware (AMD Radeon 7310 HD Graphics) to see if the issue was solved which it wasn't.

So I am guessing if the issue is something to do with the dust clogging up in with the fan near by the GPU, making the connection loose or if it's getting overheated. (Usually in Task Manager, sometimes it goes up beyond 50% depending if you have something running; like WMP 12)



Thank you!

It doesn't show the black/transparent squares all the time. But it makes the video slower, audio is okay.

PROBLEM SOLVED
I have found out why this is causing to go wrong! So when Google Chrome is open.. after a while it is open, it affects the player. So what I did was to close the browser and play the video, and it worked fine! I just don't know why this was happening, probably something to do with background processes of Google Chrome?
