Help with hard disk detection

Hello guys,
I need some help with my "Windows 7 professional" computer.
My computer is suddenly not detecting external USB hard drive
While trying to fix this issue I came across 2 further issues:
1) The command prompt window when opened closes immediately due to which I am unable to type in anything.
2) Unable to open gpedit.msc (i do have gpedit installed, it again disappears immediately)

can anyone help me out with the above 3 issues please:(

Boot your computer into Safe Mode.
Does it still exhibit the same problems?
Enable the hidden administrator's account and boot into that.
Does it still exhibit the same problems?

Thanks Noob..that was really easy and it worked! It has solved the hard disk detection problem atleast.
I am still not able to open cmd or gpedit though...but not much worried about it...atleast currently:)

Even event viewer hardly opens for a couple of secs before closing....can hardly view anything in it....
