Hey guys, i've recently been having issues when playing minecraft. For some obscure reason, it will work fine for a coupe minutes, then start lagging a ton, having a bunch of random lines and colors, then the screen goes black, and it says the conneciton to the card was lost but then recovered. Any suggestions? I've already tried editing the registries, messing withe the minecraft settings, and updating the drivers. I have a Nvidia Quadro FX 5600.
