Cyclic Redundancy

Backstory
Kinda panicking here. My computer is very slow and it failed to boot a few times. Tried a virus scan, but nothing came up so here I am backing everything up.
So I just went and copied everything to an external, but while that happened I was stopped due to a Cyclic Redundancy check on a file. To test, I tried to delete the file it but nothing. Since it was just an image, I ignored it and copied again omitting the file. But then when I went to copy my vids, it happened again and repeat steps. Went online to find out what the problem is, something like file is corrupt but I didn't understand the steps to fix it. On a utorrent site it said that the PC is dying. I guess I don't have much time...

How do I go about fixing the cyclic redundancy and save my file?

Like Tegumi's link implies, it sounds like your main hard drive that contains your OS(Windows) has bad sectors. When the hard drive tries to read files that are in or partly in bad sectors, it will most likely fail to and not be able to read all the files. Definitely follow the steps in the link above.
Sometimes bad sectors can be repaired, but most of the time it's worth more to buy a brand new clean hard drive. It is very possible those same sectors can start going bad again even after a chkdisk.

FFFFUUUUUUCCCCKKKKK!!!
That sucks diseased moose wang, Unsigned. I had that shit happen a little while back, but it was on one of my external drives, not my main drive like yours. I first noticed it through UTorrent while trying to download and seed sup epic p0rn files, and kept getting no data movement despite a completely clear internet connection and lots of seeds and peers. I see something in a status bar about a 'disc overload 100%' or something like that and 'cyclic redundancy check' or something similar and think, "oh fuck, what is this shit" and look up what the hell a cyclic redundancy was and come to the shocking realization that my beloved 1tb external drive was giving me its death rattle. I ended up replacing the drive with an exact duplicate I found on sale, but you've got it rough; if it's your internal drive that's corrupted then odds are if you can't restore it you're going to have to buy a new internal drive, install your operating system onto the new drive, and try to recover and move as much data from the old drive as possible. I do not envy you right now, that's for sure.

So that I know, what causes Cyclic Redundancy? Virus? Age?Uh, 'Cyclic Redundancy' isn't a problem. Cyclic Redundancy CHECK is a method of making sure your data hasn't unexpectedly changed. (eg. corruption)
Your question should be reworded as "What causes data corruption?", to which many factors such as power fluctuations, poor hardware construction, and bad software could be causes.
