Printer, Display Driver, and Wifi driver corrupted/gone

I am totally weirded out by this. I got a Samsung 850 Evo ssd about a month ago. (I include this because it ?might? cause the problem.) I am running windows 8.1.1 x64.

Last Saturday, I woke up and my computer blue-screened because of a DPC_WATCHDOG something or another. I was able to fix it by updating my GPU and integrated graphics drivers. Yesterday (tuesday), I went to print a document with LibreOffice and it said (copied from a dialog box):
splwow64.exe - Bad Image
---------------------------
C:\Windows\system32\spool\DRIVERS\x64\3\UNIDRV.DLL is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0xc000012f.

Okay, I think, I can print elsewhere. I continue working (still need a solution to this, part 1 of my question is: how do I fix this?).

Here is where it gets weirder, today (twice!) I put my computer to sleep, and when it wakes up, my wifi is gone boom nada. I try toggling my PC into airplane mode. I try turning Airplane mode off, wifi stays off. I try to turn the wifi on.... and it won't turn on :huh:. I tried manually dragging it to no avail. I am now assuming this is a driver issue.

Any ideas what could be causing this? I have run a full scan of my AV and am scanning with ESET online, but nothing yet.

Well problems went away... still no printer driver.
