Hi friends, I have been facing this issue since sometime now. I have a desktop with ECS motherboard and Intel Core 2 Quad (8200) processor. Initially, I tried with Windows XP, then Windows 7 and now I'm running it in Linux (Ubuntu), still no difference at all. The problem that I have been facing is as follows:- Whenever I run any videos in full screen (I do have a 22" monitor) the PC shuts itself down sometimes quoting that the temperature limit has reached for shutdown. I have tried several ways of resolving this issue but none of them materialized. Now I have come up with a doubt whether my motherboard is doing something wrong. Can anyone help me out with this? Have anyone faced any similar issues? I would very much like to resolve this issue to regain my desktop's performance back to normal. Hoping for a hint/reply soon..
