When i turned on my PC it starts but i get no screen image. Considering my motherboard doesn't support a speaker, i can't hear any beeps so i can't determine what it is. It starts as usual buy obviously it doesn't start windows because i can't hear any startup sound and the monitor stays in stand by mode. I'm guessing the most likely faulty from the start radeon 6850 is dead and i know that windows 7 doesn't start if a graphics card is dead or damaged. what do you guys think?
