Story of the last 2 weeks of my computer.
First, HD crashed. Was unable to boot into windows or safe mode. Was unable to even do a chkdsk.
I then got a new HD and installed windows and everything else. I was then able to read the failed HD which I have set up as my D drive.
Then I bought 2 sticks of 1gb ram. I originally had 3 sticks of 512mb and so I gave 1 stick away and now have 2 sticks of 512 and 2 sticks of 1gb. I installed then correctly to give me Dual Channel Mode. Then I was unable to play AH. I mean, I would fly for 20min or so and then BAM! Game just pauses. I then have to hit the reset button. I've tried many drivers for sound and video and I even upgraded my BIOS! I've even tried different ram configs like using just 2 sticks even just 1 stick. I've spent 2 weeks troubleshooting. I finally reformated my HD and only installed what I needed. I can't play this game for 5 min before it will pause. It may then come back alive and the pause again. Pauses can last a full minute.
I've tried setting sound accell to as low as 1/4.
