Thumbnails not working...

I know there are other threads with this title, however I cannot find a solution.

I have done the check the enable thumbnail view and unchecked the always show icons never thumbnails option. However this does not fix the issue. It's not just pictures in folders I am having issues with. When I right click the desktop and select personalize all the preview options are black (no pics or icons).

I don't want to have to re-install the OS so any help would be greatly appreciated.

Try using one of Windows 7 pre-installed themes (specifically Aero Themes) and work backwards from there.

I have changed the themes with one from the windows selections, everything is blacked out, i can't get a thumbnail or preview from any type of pic in any option I see.

I have reverted back to the windows 7 aero theme...

Try opening up a command line and type in "sfc /scannow" to look for errors

attached is the pic of my screen when trying to change themes...
Notice all the pic previews are black.

sfc /scannow would look for corrupt system files on your computer and it would then automatically try to resolve the issue by looking for the appropriate files

Thanks running it now, will let you know what i find

ill be here

Also, are you running the 64bit or 32bit windows 7?

I am running 64bit...also the scan is done, says it found corrupt files but unable to fix. Shows me where to go to see the details in the file, but when i go to the file and try to open it, it tells me access is denied...
