I was wondering if anyone else had this issue that while playing a youtube video and starting AB freezes computer that it freezes computer and had to hard shutdown the computer.
Hmm, I feel like it may be RAM perhaps? Try removing all RAM modules so only one is in the motherboard, then perform the same thing you have been and if it freezes again, swap that one module with another. If it continues to freeze with one of each modules installed, we can go ahead and try something else.
