I have a Radeon HD 5770 1GB 128-Bit GDDR5. It works flawlessly. Once I disconnected my monitor 1440x900 to connect directly to the lcd projector with 600x800 resolution. After that, I connected my monitor and changed the resolution to 1440x900 again back to normal. Since then, whenever I restart my computer, or I played a game lower than 1440x900, I have to manually change my setting from CCC or the screen will be a little big from my monitor. I mean the start will not appear because of the size. I have to manually detect my monitor from CCC for it to auto fit again.
And my graphic card will be very hot if used for a long time without shutting down PC even without playing any game, and the pc will BSOD and restart again, it become worst when playing games, short time until restart.
What is the problem?
