I've read a few of these threads I've seen but none of the solutions suggested haven't helped. Midway through playing a game, both monitors flash black and display a "no signal" message. I've tried using another monitor with my computer with the same problem. I left the screens black for about five minutes before I decided to reset, and now I simply can't get anything on my monitors (both of which work on another system in the house). Is there anything anyone can suggest that may help? I've tried: Cleaning my base unit. Testing monitors with another system. Testing another system with monitors. Despite seeing no image, I tried to boot into safe mode. Unfortunately, the only system specs I can remember are that I'm on Windows XP 64-bit and the graphics card (which I think may be the issue) is an Asus GTS250 DK/HTDI/1GD3 (Details from it's box).
