When I start a program with the little shield on the icon (it's the UAC i guess) it's freezing, and few minutes after, there is an error "The device is not ready". The problem is only with the UAC, i can run all other programs or games as long as the UAC doesn't ask for permission.
An exemple with the task manager, when i launch it, whatever how i do, there is the same error C:\Windows\system32\taskmgr.exe "The device is not ready". Same problem if I try to install something on E:\ only the adress is changing
Obviously I tried to deactivate UAC in the control panel, but i can't because UAC ask for permission xD If i click on "Change User Acount Control settings", the window deselect itself and nothing happen :(
I hope you can help me without reformatting my computer :'( It worked well yesterday.
Thanks for reading
EDIT: It seems that i can't launch any admin tool, such as Command Prompt (admin), when i click on it, nothing happen D:
