Hi there, I recently got a new Powercolor 6870 and have been experiencing black screen crashes while playing games. More specifically, after a seemingly random amount of time my screen will go black. The computer remains responsive for another 5-10 seconds before locking up as well. (I was once able to tell people through Skype that my comp just crashed)
This has only occurred during games and once when watching a youtube video. I have latest driver updates for my card, and removed (to the best of my knowledge) the old NVIDIA drivers from my previous 9800 GT. I also put my 9800 GT back in, and the problem went away, so I presume the problem lies in the card.
Here are my specs, and if you need more information, I'll do my best to get it.
ASUS P5QL Pro
Intel Core2Quad Q8200 @ 2.33
4 GB ram
Powercolor HD 6870
Antec Basiq Power 500w
