windows not showing internal card reader.

[movingtables]

for some reason my computer has stopped reading SD cards
via its internal 7 in 1 reader.

tried uninstalling it via device manager and reinstalling.
tried disk management (viewable here) uninstall and reinstalling.
tried re-assigning different letters via disk management.

windows 7 64bit

SD card works fine on my other computer (laptop)

Is it a USB card reader or part of the PC case? Are there any associated BIOS settings with it?

compressed air from poundlad sprayed into the internal card reader.
