Sometimes the computer freezes completely. I shut it down, but the top 1/5 of the screen still shows what was on the screen when it froze. The rest is the black of the shut down. It can freeze in a desktop screen, if I step away for a minute. It doesn't always happen. If I am playing an MMO online, it can freeze when the action is going on, or during a quiet time. It can continue to play well also. It can pause for a few seconds a couple of times, then be fine again. Or not pause at all. My system, Win 10 Pro is current. I uninstalled all the drivers and reinstalled them. My other drivers are current as well. The event viewer doesn't show any problems at the time that it freezes, either. Given the sky high prices of graphics cards now, even without the new tariffs, I'd like to be as sure as I can that it is the graphics card. Any thoughts are appreciated
