Am I the only one getting this? It seems like when I'm viewing streaming video (NFL Preseason) and YouTube videos, my system crashes. The screen goings all grey and it tells me in 4 different languages to turn off the system by holding down the power button for 3 seconds. I do all of this then I send an error report to Apple when it reboots. I know its pretty rare to get a virus but do I have one? I never had this issue before till a week or so AFTER I installed the Lion update. Help, it seems like this is happening like 1-2 times a day. Its very frustrating. Thank you!!
