Gateway P-7805u FX HDMI Screen Goes Black After Short Time

[Collin Moore]

I have a Gateway P-7805u FX laptop. I recently (~6 months) bought a 42" AVOL(AWOL?) 3D TV and have been using the HDMI port on my laptop to use the TV as my screen. I haven't had problems with it until within the last month or so. After anywhere from 20 minutes to several hours of gaming, the screen goes black and says no input. I usually have the laptop screen turned off through Nvidia Control Panel (I tried leaving them both on and both screens go black when this occurs.). I would normally call this overheating, but since it started happening I've set up a big tower fan next to the laptop and have had it blowing on it constantly. The temps never read over 40-45c, even during games.

What's strange to me is that the sound keeps going, and not just a small segment. If I'm listening to a song on Youtube in the background while playing and the screen goes black, I can still hear the entire song play. I've tried cleaning dust out of the fans, doing a clean Windows install, taking the bottom covers of the laptop off to make sure it's getting all the ventilation it can... I'm out of ideas and it's driving me insane.

I'm running Windows 7 Ultimate, 64-bit. I just reinstalled 2 days ago and installed all of the Windows updates that were available. I'm running the latest stable build of Nvidia 9M series drivers (as of 2 days ago). The only thing I can think of that I haven't tried is removing the RAM and trying a new stick. I've got a pair of 2GB sticks that came with the laptop when I bought it and haven't touched them since the problem occurred. Any ideas? Help would be greatly appreciated.

You either have the monitors set to turn off in power management or the video card is crashing. Try deleting the card from the system and re-install with the latest drivers from Toshiba. Do not use the drivers from Nvidia.
