My Son Has Brought Me his Laptop used for watching cartoons on.
The Screen has a Blue background with white writing and a sad face icon and the following words

The computer has not restarted and could have been like this yesterday I cannot find out.

Thank you Ken for your interest. The Problem with the Acer Laptop has been solved. I did notice that the power light was indicating low, so I charged it a little and took it back to Argos where it had been purchased 35days earlier, Itself a replacement purchase for a previous Acer also about 35 day old when I got my money back and bought the current one.
I kept the screen on blue as I wanted to show the manager the blue screen and message, however in the shop I left it with the manager and went to my car to get the receipt, on return the manager had press the buttons and it appeared Ok, Took it home again. Apparently solved!

However My big Problem is still My Medion PC of a few years old.
My Problem is that I have so much data going back a very long time from early Windows that I cannot risk just feeding it into a problem solving set up and one day find some docs that may have been moved many times finding them vaporized, as the long links could have been part of the problem. I did try AVG, as in the past they have taken over my computer and solved a problem before now. But they say the Problem is with Microsoft. I think so too. It looks as I have an App index blown up and placed over my Folders-I cannot modify it at all - Make it smaller etc. to expose my Desktop. I can on a slightly longer roundabout way still access my data, I did also put a message on the Microsoft website, but got no reply.
Out of interest I will reply to the thread with a two screen shots if I can. Just to let you and others see the Problem and may recognise where this "app index" has originated from it looks similar to my previously index that could be popped up when wanted and removed with a click on the desktop screen. But it has also taken out my taskbar.

How can I Paste a word document containing two screen shots into a reply.

axeO I could not show these screen shots from word I had to use the email attachment and a copy of the image saved from the paint Program after selecting and attaching - only a line of Code was displayed and was transformed during the sending
