Hey again, fellas. Just a little update on my USB freeze issue: I visited my local MicroCenter this morning and picked up a WD Blue 1TB SSD, cloned installation from the M.2 onto the SSD, reset SMBIOS and other necessary information, and it's now been running all day without any hiccups, everything working 100%.
Will probably leave it running tonight as well to test the longevity of it, as I will deliver it Wednesday morning this week. I know M.2 drives in general are "supposed" to work, but I think some are hit and miss. A lot of guys have had good luck with Inland M.2 hack builds, but I really believe I wasn't one of them. The M.2 drive we have was erased and partitioned to be used solely as extra storage in his system. Hope this helps someone out in the future! Thanks guys!
