I was playing civ 5, when the screen went all wonky with colours then it went black. I shut the game down and retried it. Same problem only it occured faster. So it progressed to the point where i cant even see windows. So i took out my graphics card and went on onboard video card. I got windows again, so i thought it must be my video card. So i went an bought a new video card, the problem is still there. I cant see windows properly. So i went thru onboard, went to windows, installed the drivers. Plugged my video card back in and still everything is gibbled. What is my next step to do? Is the problem (hardware) more than just the video card? Appreciate the help folks.
