I was surfing the web and fed up with popups reminding me of things I had previously looked for I clicked on private browsing on the toolbar, thinking this might stop it. Back toi the web, changed pages and the whole screen went white. All that was left was a hand icon in the middle. I tried alt-ctrl-del without any result. So I turned the laptop off and rebooted. It boot the "welcome to windows 7 screen then went on to the white screen, where it remains.
There is no border, no taskbar, nothing except a white screen.
If I press alt-ctrl-del I get the page showing :- "lock this computer, switch user etc and start task manager." None of them work, it just reverts to the white screen, however, on the bottom left is the "Ease of Access" Button. If I activate one of these commands I can now alt-tab between the command I have activated e.g.Magnifier and (apparently) Windows Logon, which is the white screen. It doesn't always go to windows logon though, it sometimes stays on the Access page.
When it does go to win logon and I alt-tab there one of the icons in the middle, in the alt-tab box, now says "Win Locker".?
On the bottom right of the alt-ctrl-del page is a red "Shut Down/Shut Down options" button. I can use this to shut it down and that is pretty much it.
When it does shut down, it goes to the screensaver page and hangs for a while with the message "Waiting for programs to shut down" and shows the "Force shutdown" buttons. Then eventually it closes the box, and the "Start" button on the taskbar appears briefly, but I can't do anything with that. The laptop then shuts down.
I have gone into the BIOS and turned off the wireless adaptor and reset the boot options to select cd and memory stick first.
Have I been hijacked or did I just press the wrong button somewhere?
I can't load anything straight through the cd or memory stick while this white page is there but I did get a copy of the AVG rescue cd which I can load, but I am not sure what I am looking at.
I haven't yet tried the manufacturers rescue disk as I am kind of hoping it will be something stupid.
All and any help appreciated.
