Web Browsers Freezing Mountain Lion
I upgraded to Mountain Lion over the weekend and I am really beginning to regret it. I went the upgrade route and soon after the upgrade was performed I began to experience system freezes while using Chrome. After a couple freezes I thought it might be best to use Safari. The problem occurred while using Safari as well. To the best of my memory these crashes generally occurred on pages that contained video. I can't say for sure because I may not have reached the bottom of the page before the freeze occurred. I performed a clean install after many freezes but the problem continues.
The freeze begins with a fraction of second where small squares appear on the screen. The screen then freezes but audio continues. During this time I am able to move the mouse but am unable to click on anything. Only option at that point is to use the power button. A crash log is not generated in the diagnostic reports. I'm not sure what is helpful to paste from the system logs but will provide anything you ask for. I'm a reasonably technically literate user but completely new to the support forums as my previous Macs did not have any serious problems.
I am a graphic designer and this is my primary machine and browser crashes are seriously inhibiting my ability to build websites. I would greatly appreciate any advice you can offer.
Below is my system as it is now. Crashes occurred even with a bare bones fresh install.
