Geez, apart from ceejay's first answer, everything else would confuse perhaps even EA staff.
You bought a brand new PC?
Do you still have the old PC by your side and external HDD? Cmon, external HDDs are cheaper than stuffpack nowadays... Well... Almost...
1. If no, skip to point #2.
- Copy all Origin Games on external HDD from your old PC
- Download and install Origin on your new PC, log onto it
- Copy games from external HDD to your new PC in the folder used for Origin games, you can see it here in Origin client:

- For each game you transferred, press "install" button inside Origin client
- Origin will detect there are files already on your HDD, will just verify files and patch if necessary
Superfast and no need to wait for ages till games unpack from CDs or download over internet.
Done? Off to point #3.
.
2. Sadly, it won't be so fast as point #1.
- Download and install Origin on your new PC, log onto it
- If you have physical CDs/DVDs, use them to install games! Installing from CD/DVD is usually faster than downloading the whole game (or DLC), unless you're on some 1TB Mbps link. Installations will lead your way, but it's mostly enter the installation key from the box, then next, next, ..., finish. If you receive a message that the key was already used, abort the installation, go offline (disconnect from internet) and run the installation again.
- If you don't have physical CD/DVD, or that particular software refuses to install without internet connection but yelled "already used key", you have to download it and install it by pressing "install" button on the game (or DLC) inside Origin client.
- It doesn't matter what's the source, optical media or download, Origin doesn't care, it's all good.
.
3. Some mention some license copies, 5 max, something about freeing a spot to install...
- Just forgeddit. You're good to go without thinking about that. If for some reason games refuse to run, quickly post in Technical Section.

You insert_something_that'd_be_censored!!! So everyone learns you got a new PC before me. Why thank you!
;)
Seriously, what hardware? Can you please post specs (hit windows key + R, enter dxdiag then press ok, post names of processor and display device, also amount of RAM)? Does it have SSD inside? Man, I'm so happy about you.
