Windows 10: Strange desktop problems?

I've got a problem with a friends Windows 10 all in one computer, something happened (he can't tell me exactly what) and now the desktop appears like this:



I can't right click on the desktop to get the desktop context menu; in general there don't appear to be any desktop icons however for brief moments when I hover the mouse cursor over an application on the task bar I can see what should be the desktop but when I move the mouse off the desktop goes back to the picture above, I can't seem insert more than one image so additional images will be attached below.

Also when you open any application it appears to be stuck in a maximized state, you can minimize it but you can't restore it nor use the mouse to change the size of any program window.

Idea's on what this is and how to fix it?

Strange boot problem

I am trying to get my head round the 6 steps above before having a go. If you can expand on them it may give me a bit more confidence. I cant lose the whole contents of my PC.
Have attached details as you suggested.

 

Windows 10 1709 System Restore problems...


That seems to be an attempt at Option 2 in the tutorial, which requires you to
a. Boot to a command prompt (Did you?)
b. You then seem to be mixing steps 3,4 and 5, thus your command is incorrect.

I suggest Option 1 is easier.

If you still have problems, please repost listing each specific step and saying which option from the tutorial you are using. Thanks.

 

8800GTS problems.

Seems pretty strange to me. I have a standard 8800GTS, the only problem I get is the BSOD nv4_disp.dll thing, which in my case I think is linked to heat on other parts of the video card.

I would suggest completely removing the drivers using Driver Cleaner, and install the ones that came with the card first. If the problem continues, remove again, try the newest drivers. If it still happens, underclock the card and try the same steps. In the end, talk to EVGA and see what they tell you.
