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 - Newegg.com)

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