Built the computer in December, after the worked great for 3 months. Turned the computer off, woke up turned back on and Everything started up, however no display on my monitor. I noticed there were no beeps as the computer started up. I thought it was the video card, I called the manufacturer and they replaced video card (msi Hd radeon 7970). Finally received my replacement video card yesterday. Installed it and now the same problem. No display, no beeps. Every works correctly, all lights on motherboard, fans all spinning, video card turns on, and all drives startup. But just no display. Please anyone, help! Very frustrating!
