Lag moving between programs/tabs/windows after adding RAM

I recently installed more RAM in my desktop since I was right on the border of my 8GB during gaming or intense internet browsing. I looked up the exact RAM I had ordered in the past from my newegg history and ordered another set of 2x4gig sticks. I installed the new ram and it was recognized and seemed to be functioning fine, but now I have 3-5s of initial lag in almost every program when i switch over to it or change tabs. Also HTML5 videos take a few seconds before they start, and after resuming the video the audio and visuals are out of sync for 10s or so.

I checked my bios and the the cas latencies and voltages are correct, I was wondering if there are any other fixes to try?

My Build:

OS: Windows 7
Case: NZXT Phantom 410
Mobo: ASRock z77 Extreme4
CPU: i5-3570k
GPU: MSI GTX 980 Gaming 4G
PSU: Seasonic SS-750KM3
RAM: G.Skill Ripjaw 16(4x4GB) (G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBRL -

edit: my virtual memory is currently set to 5-7GB(windows recommends 24GB). I only have a paging file for my main SSD

Just adding RAM would not cause this - assuming the RAM is compatible and not faulty, and is fully seated in its slot. So I suspect something else happened during the installation process. Perhaps a cable was knocked loose.

Did you unplug the computer from the wall before doing anything inside the case? Did you touch bare metal of the case BEFORE reaching in to discharge any static in your body? Did you ensure you properly handled the RAM by NEVER touching the electrical contacts or getting it near an ESD source?

SSDs are ideal for Page Files so that is good there. But there is no harm in enabling paging on your other drives. Windows is smart enough to sort it out and optimize as needed. And unless running critically low on free disk space, I always recommend letting Windows manage the PF too.

I would remove your new RAM and see if the problem goes away. You could have gotten some bad RAM. It happens. Also, if your empty slots were empty for a long time, they could have become dirty with dust and grime. While I don't normally recommend reseating RAM that has been working fine (these slots are designed to keep dust and dirt out of them when RAM is properly installed), empty slots can still collect a lot of dust and reseating often scrapes the contacts clean. Just be sure to unplug from the wall and observe proper ESD precautions by touching bare metal of the case interior BEFORE reaching in or touching the RAM.
