Three thoughts;
Drive "C" on most systems contain the operating system and will not "auto-play".
Deleting Programs is the best way to cause re-install of operating system.
Detals on system and issue.
When I go to My Computer, then the C: drive icon I get the message "Windows cannot find Autoplay.exe" I think the path for the C: drive has been corrupted. It seems to be pointing to a programme I deleted. The drive icon has also changed to show the generic Microsoft Flag. I can access the drive but have to right click and use Explore.
