How to replace hard drive?

[3045257]

Okay my toshiba 500gb is "failing" or whatever. Occasionally I'll hear a clicking noise and then the computer basically freezes, windows has also told me my hard drive has messed up. No big deal, I buy my new hard drive. How would i go about replacing it? I know how to stick the thing in my computer, but how do i transfer everything over? I've looked up cloning or creating a system image, but no clear tutorial on how to do that. So how would I do it? The bad hard drive still functions 90% of the time, i can get data off of it. I dont want to redownload everything, ive had to do that once when windows screwed up. I cant get acronis or id use that. I dont know how to use clonezilla for my needs, ive seen tutorials talking about laptops, ive got a desktop.

Disconnect the failing drive
Install the new drive
Install Windows
Once everything is working...then see about connecting the old drive and retrieving data from it. The more you mess with a dying drive, the sooner it will actually die.
