I have the oem aimtrack modules and have been working great for years on my mame cabinet with a duel core setup. I updated to a i7 2600 hp 8200 elite cmt and everything seemed great, was way faster but after the 5 or 6th boot up it would boot very slow on the loading screen it would hang until I unplugged one of the guns then it booted? then sometimes I would loose one of the guns in mame. sometimes they worked. I reinstalled windows and eventually it acted up again. any ideas? I am thinking its a usb problem and am thinking of getting a pcie usb card to separate the guns from everything else. anyone else ever have a problem like this.
