My Asus UX501VW laptop screen goes gray and stops working. I installed an Intel display driver from ASUS site and it stopped. I went ahead and updated all the drivers for my laptop at Asus. It was good for about a week and now stays on about 40 seconds and then goes gray. Here is a link of the problem:
After screen went gray, I held down the start button over 15 seconds. Restarted. Repeated 15 seconds to restart. After three times computer entered "automatic repair". Restared and computer entered diagnosing PC. Now it starts fine and is repaired.
