The problem continues: This time I was working in PS. Suddenly the screen split in half, reversed, and froze. By split in half and reversed, I mean that the left side appeared on the right, and the right side on the left, like vertically cutting a piece of paper in half and sliding the two parts past each other. Even the icon bar at the bottom did this split. I could still move the cursor, but only within the PS window, and I couldn't make any commands with it. When I powered down the computer and just a couple of minutes later restarted, as soon as I logged in, the screen went gray again. I turned the power off, went and did something else, then about an hour later it booted up. Also, the new file I had crated in PS and been working on was lost, even though I had manually saved it during the work.
Any ideas?
