Whenever I get problems such as this I try the System File Checker (Start - Programs - Accessories - System Tools - System Information; Click the Tools tab and click System File checker). I don't know if it'll work but it won't do any harm.
Mmmm. Well you could click 'Start' then 'Find' and select 'Files and folders' and tap in System File Checker. That should find it for you. If it does you may be able to d/click it in the window and I it may open up for you.
I'm sorry but i have know idea about video software/ not been on computer for long.didnt realise i had such software? can you give me some more clues, sorry about this.
With your computer you should've been given some software on CDs. Find the one for your video and check its name. Then go to 'My Computer' and d/click 'Control Box'. D/click 'Add/Remove' and find that software in the list. Highlight it and click 'Remove'; you may have to reboot. Place software CD in CD tray and reinstall it.
nview.dll is the nVidia desktop and windows manager. You seem to have a video (or graphics) card made by the company nVidia. These cards include the GeForce and TNT cards. You can try to register the dll (start > run > type: regsvr32 nview.dll then OK) or reinstall the nVidia graphics card drivers. Go to here for the latest drivers (you must know the graphics card you are using) http://www.nvidia.com/content/drivers/drivers.asp
