ya they are two seperate folders.

"C:\Games\World of Warcraft\World of Warcraft\WoW.exe"
"C:\Games\World of Warcraft2\Wow.exe"

a mem test wouldnt be a bad idea..

At first only one window would crash.. I updated every driver on my computer. Now i can go about 30mins worth of playing if i keep the pally minimized. But as soon as i start clicking between windows. Thats when the problems start.
