I recently updated my Skype to the most recent version. However, ever since then, I have had problems with my computer freezing for a short period of time before inverting the colors, doubling the screen resolution, and reporting a problem with the igxprd32 display driver. I have plenty of space on my computer and usually, this happens when I only have the Skype service running while I text/chat with friends. There's no reason that I can see for this to keep happening and it's occurred several times today already.
