If this happens on a PC, you can just swap out your Video Card, but on a laptop, your laptop is doomed.īut if you ran ALL of the tests and it didn't freeze up and you got THAT score which is better than the 820 I got last time I used it, then there is nothing wrong with either your Ram or your Video ram. the Video was Dedicated and nothing I could do to fix it. That happened to me with my old Dell Laptop. You use the Video Tests for that program, and if your system freezes up during the Windowed 3D test, you may have a bad stick of ram on your Video Card. Actually, I forgot to say, check for a Video Memory error.
