First off, my setup is a Dell XPS 7100, Windows 7 Home Prem. 64bit, Visiontek AMD Radeon HD 6850 Video Card w/ version 188.8.131.52 driver,
AMD Phenom II X6 cpu.
My problem is that when I try to play any game (more specifically: Minecraft, SimCity, World in Conflict, AOE3) on Windows, the screen will freeze for about 5 seconds then go black for 1 second then come back up with an error message saying:
Display driver stopped responding but has recovered
Display driver AMD driver stopped responding and has successfully recovered.
This only started after I upgraded my video card from a AMD HD 5670 to a Visiontek AMD Radeon HD 6850, which at the same time I upgraded my power supply to a 500w unit like AMD recommends. After this occurred I updated all my drivers, deleted and reinstalled the video driver and that did not help. I then searched all the forums talking about this problem and found that it is more than likely a problem with Windows Power Management. So I followed the instructions from this site to change the registry data to help with this. This did not work, the same problem at the same times. I then contacted AMD Support and they pretty much told me it was either the power supply or windows power management that was causing the crash.
I'm at a loss now, I'm not sure what to do. I haven't tried any third party programs to try and manage the power. But if anyone has used one that works or has any ideas for me to try please let me know.
Thank you very much!
