Does anyone else have a problem with adobe flash player causing CPU usage to run high after watching videos? I'll be watching videos and then after a while the tower/hard drive makes a weird noise like it's being overheated or dying.
What are your specs? The GPU on any modern system should do the video processing, leaving the CPU without a lot of usage. It's either a fan or the hard drive. Take the side panel off and try to find out what's doing it.
