The dates on your dump files seem a little strange, the most recent I see is 3/3/2014.
In that particular case it appears it may be related to your wireless chipset.
FAILURE_BUCKET_ID: X64_0x9F_3_POWER_DOWN_bcmwl664_IMAGE_pci.sys
Is it possible you can look in device manager and let me know which wireless adapter you're using, I can then direct you to Broadcom's page to obtain the latest driver.

Hmm.. well Windows itself could be corrupted. Did you complete the system file check asked about above? If not try running one now:
