Open the case, and after grounding yourself, proceed to press down along the length of the video card. My guess is, at some point, you'll feel it slide in a little and the system will start afterwards.
I recently install a new graphics card ( ATI radion 9600 XT) and was playing one of my games ( Dawn of War ) when the game froze so I pressed Ctrl+Atl+Delete then the start buttton and they both did nothing, The Pc was completly frozen so I pressed the manual reset button, The pc did not start back up. I got a blank screen and the light on the monitor was the one I get when my PC is turned off. not only this but the tower is making a beeping noise and both the red and green lights are constantly on but flashing very very fast. If any one has had this problem or can help remidy it please contact my at email@example.com asap,
