I recently bought a HP a6040n mid tower pc and I'm having a problem. When I hit either the shut down or the hibernate button it will shut down all right, but then the power button stays on and the fans go full speed. I press the power button again and it comes back on like normal. I only want my pc to shut down completely. Here is what my pc has ÃƒÂ¢Ã¢â€šÂ¬Ã‚Â¢ 2GB of DDR2 memory ÃƒÂ¢Ã¢â€šÂ¬Ã‚Â¢ Intel Core 2 Duo E6320 ÃƒÂ¢Ã¢â€šÂ¬Ã‚Â¢ Windows Vista Home Premium I put it a new video card and power supply on it recently too. My Power Options are on the Energy Star option, on the defaults. Help please?
