Random BSOD

Hello everyone, I have been getting random BSOD lately. I had this issue in the past, and memtest diagnosed a bad stick of ram. Well the other day I got a new hard drive and for the fun of it I threw that ram in again to be sure it wasn't a fluke or improper seating or something along the lines, and it began crashing again. So I pulled the ram out and it was still crashing. I put the ram back in and ran memtest overnight and woke to not a single error. I then ran prime95 and unigine heaven at the same time while at work to test the stability of CPU and GPU while at work all day, and came home to no errors. I proceeded to use the computer for the remainder of the next few days without an issue. Today I went to shut the computer down and got the BSOD during shutdown. All my drivers have been updated, and windows as well. I tested both my hard drives in linux with a long selftest with no errors. I'm not sure what else could be the issue. Here is my specs

Windows 7 home premium x64
MSI big bang mpower z77 motherboard
i7 2600k
Sapphire 7970 6gb
1x 1TB HDD
1x 4TB HDD
4x 2gb Gskills 1600 DDR3
seasonic 750 Gold cert,

I will also upload some error info I got after the most recent crash. Thanks in advance.
I'm not sure if the program "WhoCrashed" is reliable or not, but this program is telling me that my USB 3.0 drivers are causing the crash. I'm going to see if I can't find an old version of the drivers or something more stable.
