I have had two crashes today that were completely random. The first crash was while in a game. The monitor would freeze shortly after the keyboard and mouse would shut off. This first crash I was forced to hard restart. The second crash I was simply watching something on Hulu. The sound kept going for about 20 seconds when the monitor went unresponsive, as well the keyboard and mouse went off again. This time it restarted after the sound started fuzzing. I did a system restore earlier today after the second crash, and thus far I have been either lucky or fixed the problem. I'm not sure I have fixed it so I figured here would be the best bet to try and see if it is still an issue.
*Unrelated* Also is there any way to change your display name? I have searched through the profile pages to no avail.
Thanks for any help beforehand.
