I am not sur if this has anything to do with your problem but i give it a shot, just don't quote me on it.

go to start menu, search/find (depending on your operating sys.) under folder/file name type *.tmp once all the files are found and comp stops searching, empty delete all files that come up. usually just cookies n crap like that. like I said dunno if it'll work but it sometimes works for older machines and operating systems.

sorry if i'm wrong
