After a certain amount of time on the internet, watching a movie, or playing a game on my pc it keeps happening. its almost like the frame rate slows down or something. Im not really sure what to do about the problem. I updated and ran avast virus on my computer it found one and took it off. and also ran malawarebytes and it found one and i took it off. i think the virus was called "video hyjak" so i was hoping that would fix the problem but its still doing it. im going to try and defrag my computer before i go to work but im sure that wont help it probably just needs to be done. any suggestions. thanks.
