An MD5 hash (Or SHA1, or some others) lets you compare two files or strings on a per byte or per bit level. If the MD5 hash of your download matches the known good MD5 hash, you can be certain you have fully downloaded it, there were no errors induced, and that it is a known good copy and not a malicious version.
There are a number of free utilities to calculate the MD5 hash of a file. I've not used them in years, so no idea what the current best ones are.
As far as known good hashes go, Microsoft (especially for TechNet) usually posts hashes for their downloads. Along with a few other companies I can't recall. Nvidia does not appear to post hashes for their drivers, so it would take a few people who have downloaded it to report their hashes and see if they gathered a consensus as to what it should be.Edited by zinfinion - 10/10/12 at 7:51am
