Prob on startup

Hello,
hey im facin a prob where as the comp reboots n the startup screen pops a window pops up sayin "Windows cannot find '"C:\Documents'. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.

after i click on ok to this prob it another window pops up sayin "Could not load or run '"C:\Documents' specified in the registry. Make sure the file exists on your computer or remove the reference to it in the registry.

after i click ok on that window then another window pops up where the same prob occurs with 'and' then 'Settings\Simran then 'My name\Application then 'Data\Adobe\Manager.exe'".

i ve tried solvin the prob by repairin windows den the solution in registry editor relatin to BITS.

the prob stil persists. also it is hamperin my broadband. i can surely download at a gud speed but cannot open any site. the site opens but sub - site relatin to the home site does not open up.
