..your explorer.exe is corrupted! your operating system!..i hope it helps!..^_^..

BlackFoot is right... your explorer did not start. Could be corrupted, could be the registry entry to start it is corrupted. So, to see if it is the former use TM to run explorer.exe . If it does not start [no icons etc show] then copy in the file from another system to Windows\explorer.exe
If your browser works [start it via TM eg enter firefox.exe, or iexplore.exe] - you won't need a pathname because the path will be in your environment settings. Use the browser to open files etc.
Registry entry bad? In TM run regedit.exe, and this is how the key should be:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]//
If that entry is not correct then this will put it right [and do no harm if you run it anyway]:
==Please copy the text in the box to a notepad [format/wordwrap unchecked] and save as fixkey.reg to your desktop; dclick it to run... agree; if it opens in notepad instead rclick the icon [file], choose Merge, else choose Open with, Registry editor....

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
