Video Card crash - Dual monitors = no video output anywhere - no sound.

I had a video card crash the other day while playing Diablo3. All the sudden both monitors lost all video and they went to sleep. The computer was still running and everything was still working ok, but there was no output from the video card. I rebooted the computer - no video. Didn't want to enter panic mode yet, but after several reboots I decided to open up the case and use some compressed air to clean out all the dust and my fans. I took out the video card and reinserted it - booted up with still no video output. I then unplugged my second montior and then boom - video to my primary display. - I have since tried several times to connect the second monitor, every time I connect it - i immediately lose all video output. I can remote into the system and everything is working fine, but no video to the monitors.

I then decided to just stay with the one monitor and take a break, but then I realized there was no sound!!! I tried unplugging and plugging back in my speakers- i disabled the sound in device manager and enabled it - i uninstalled the sound driver and rebooted to have windows reinstall it - still no sound.

I can live with 1 monitor (barely) but I cannot live without sound.

Any thoughts? Did my video card overheat and short the sound from my mother board? (i use integrated sound).

I am using Windows 7 64 bit

  1. Any ideas why a bad card would affect my onboard sound? I have a sound card coming today. I still bet a black screen crash if I try to use both DVI prots. Is this card toast?
  2. Perhaps try reinstalling your video and sound drivers in safe mode, then Diablo after rebooting. ? Good luck to you.
