# To delete a corrupted IE cache and build a new cache
Yes you can. It will actually make your PC run faster. Assuming you mean your browser's cache, then you can certainly delete (or clean) it without hurting anything. However, the browser cache is there to speed up the displaying of pages, so after you clean is out, your browser will render pages slower for a while, until it fills the cache back up with your commonly-used items. Browser caches are also the place where things like automatic login cookies are stored, so by deleting your browser cache, you will be prompted for a password the next time you try to access any password-protected web site. Caches in general work this way: they are a place to temporarily put things which are commonly needed. Thus, a cache can be cleaned out or deleted without impacting the functionality of your computer - that is, they perform no ESSENTIAL function. However, they provide a (significant) performance increase, as a getting things from a local cache is always faster than getting from the original location. If you are referring to cache memory (frequently mentioned in the specifications of a CPU chip), this cache is part of the CPU hardware itself, and cannot be turned off or deleted.
