My Asus laptop has a problem. When I start it/unhibernate it I get a grey screen. Sometimes I can just close the lid, open it again and everything is fine but other times the grey screen persists through numerous attempted restarts.
The computery bits are working as it still makes the relevant bink-bonky noises. If I time it right I can also enter my password to unlock it (can here the "bing" noise when the password is accepted), even with nothing but grey on the screen
Once it's running it's absolutely fine but the moment the screen goes off (if I don't use it for a few hours) it's back to grey screen on trying to wake it up again.
