Random BSODs with Windows 7 Pro, 64-bit on ASUS B85M-G Motherboard

[Bordermancer]

I built this system 5 months ago and have had several random BSODs averaging 1 per week. I recently added a second 8 GB RAM stick in addition to my original 8 GB stick. They are as similar as I could get, since the original model is no longer available.
Orig: Patriot Viper Xtreme 8 GB PX38G1600C11, New: Patriot 8 GB PSD38G16002H
both are DDR3, 1600 MHz, PC3-12800, CL11, 1.5V
The memory is not running in dual-channel mode.
My hard drives are:
orig. WD 500 GB (WDC WD5001AALS-00E3AO)
recently added: Samsung 250 GB SSD 840 EVO
I migrated my C: drive from the hard drive to the new SSD
I have always gotten occasional BSODs with this build but recently they have increased in frequency to about 1 per day. The BSODs seem to be truly random and I haven't been able to relate them to anything in particular that I've been doing.
I ran the SF Diagnostics and have uploaded the results.
Please review it and see if you can find my problem.

Not able to update USB 3.0 Extensible Host Controller Driver

I appreciate Golden's reply but I was unable, after many tries, to update my current Host controller driver,
iusb3xhc, v. 2.5.0.19 to the latest v. 3.01.41. I first tried directly from the Windows Device Manager. It told me I already had the latest version. Then tried the download from the Intel website. It ran part-way through but failed to update, leaving me with NO Extensible Host Controller installed, then tried the ASUS support site. It gave me a download that looked like an exact duplicate of what I got from Intel. Same failure and bad results. I made certain to run Windows System Restore between my driver update attempts so I would be attempting each update from the same driver environment. I also disabled my anti-virus program temporarily. I finally ended up reinstalling a fresh(?) copy of the v. 2.5.0.19 driver. It hasn't blue-screened yet, but my latest install was only 15 minutes ago.

Not able to update USB 3.0 Extensible Host Controller Driver

I also ran Memtest on each of my 8 GB memory modules for several hours last night and ran a full chkdsk on my C: drive. No errors with any test.

Keep us posted and upload new ZIP file if the system BSOD's again.

Please check for an update for Quicken 2014.

For your USB drivers, I'm afraid the only thing I can suggest is to check with the manufacturers support forum.
