Having coh troubles, need the help of kind strangers
I am not 100% sure that a video card change would cause a mapserve - I tend to see it when my internet connection is being sucky (vent has high pings, web pages are slow) - So if you can eliminate your ISP then I would look to and update your network card drivers. For me any sort of latency causes me a mapserve - yet my ooma voip stay steady and just fine...usually I can track it to a ms drive update for my network card and I will chase down the makers latest driver and all is right again with the world.
Here are my two system reports. I've had mapserve problems for some months now. I was running this game on a geforce 8600 prior to buying the 430 and I didn't have mapserve problems then. True I had to run the game on the bare minimum settings but no mapserving.

Now even on the absolute minimum settings I'll mapserve. I know it shows High character but I have run this game as recently as last week on the bare minimum settings across the board as well as no sound.
I realize things might go smoother if I had a wired and not wireless connection but like I wrote earlier I did not have mapserve problems a few months back running the game on geforce 8600.
Any help is greatly appreciated.
