OK, I went into my driver cache, then clicked on a file called i386, and clicked on driver in it, and found a massive amount of files with a bunch of names ending with .dll. Examples include hpvimn50.dll, epnhte4k.dll, lxsddr1.dll, cqsddr1.dll, etc. and some of them repeat, having the same names as others.
Is that normal? If not, how can I remove them? The only options I have when I right-click one are Copy and Extract, and they can't be deleted.
