Constant freezing, and horrible loading out of the blue.

[cicrops]

At the moment, my Windows 7 machine is freezing, up to a minute, then resuming normal operation for about 30 seconds, then the freezing continues. I'm not quite sure what is causing this. Also, when the computer is having a clean streak, without freezing, occasionally windows take a very long time to open. Help would be greatly appreciated.
As for recent things I have done, I've just attempted to update Steam due to an error, but other than that, nothing else major has been done to my computer.
