Did the system manufacturer provide you with Windows 7 recovery DVDs or are you running a full retail version Windows 7?
I noticed these NEC USB 3.0 drivers -
nusb3hub.sys Fri Nov 20 05:15:57 2009 (4B066C5D) - NEC Electronics USB 3.0 Host Controller Driver
nusb3xhc.sys Fri Nov 20 05:16:01 2009 (4B066C61) - NEC Electronics USB 3.0 Host Controller Driver
Where did they come from? Do you install them post-Windows 7 reinstall or are they on the Windows 7 DVD?
I would wipe the HDD with KillDisk, reinstall Windows 7 again.
KillDisk --> Format HDD jcgriff2.com
See if driver update available -
gdrv.sys Thu Mar 12 23:22:29 2009 (49B9D175) - Gigabyte Easy Saver - mobo power utility driver
After Windows 7 reinstall, allow ALL Windows Updates in. Also, given the numerous changes in hardware, validate the OS at Microsoft WGA site -
Windows Updates --> www.update.microsoft.com
Microsoft WGA --> www.microsoft.com/genuine
Should problems persist, please provide additional system information. Follow the instructions, attach the resulting zip file(s) to your next post. BSOD Kernel Dump & System File Collection - jcgriff2.com
After attaching zip files, run the Driver Verifier -
Driver Verifier --> Driver Verifier - jcgriff2.com
Doing the above will hopefully help us to determine if software is a viable culprit or not.
