(this will sound like a rant, but it's just a bunch of important things to take into consideration)
Where did you download the replacement .dll file from?
And what is the name of it?
Has it been scanned for trojans or other malware?
If it's replacing an exisiting DLL that is corrupt, but loaded into memory at boot, you'd have to boot into safe mode to prevent windows from locking the file and then replace it.
If it's a DLL from an app, reinstall the app.
If it's from Windows, do an emergency recovery from the CD, then reinstall service packs.
If you're not familiar enough with the PC to be able to find them on your own, as Ken said, you shouldn't mess around with them.
And never, ever, install DLLs the originate from a third party. Like a site you'd find on google that provides DLLs.
Some of the stuff people hide in those is comparable to leaving copies of your housekey on the front step with a detailed list of valuables.
