Windows 8 Computer Crashes / Won't Work With Updates

So the problem started about a week ago. I came home from work and tried to wake up my computer. It "woke up", but only to a black screen with cursor flashing in the middle. It was clearly on the User login screen as the ease of use button in the lower left corner kept flashing periodically as well. I tried tying in my password and nothing worked.

So I began looking online and I tried some suggestions: Bringing the System Recovery and entering safe mode(same thing happened)....tried entering safe mode + cmd prompt (same problems).

I then used the System Recovery, cmd prompt, and robocopy to transfer all the files I needed to an external...so those are all safe and sound.

I tried doing a system restore point, but that didn't work either. So fed up, I decided to do a clean install. I inserted the disc, deleted the partitions and everything on the hard drive, and just did a fresh install of Windows 8.

I FINALLY got to my desktop. So to get back to 8.1 I had to do all the appropriate updates...which is where I ran into problem #2 that plagues me till now. After the updates were installed it, of course, asks me to restart...when I do.. I get the windows logo with the swirling dots and then BSOD.

The error on it is "SYSTEM_SERVICE_EXCEPTION (nvlddmkm.sys)". I read that thats because of video card drivers....so I go back to a system restore point I set up, and try updating without the gpu drivers.

I get the BSOD again and same error, though this time without the "(nvlddmkm.sys)".

I went back, tried updating BIOS, tried updating things one at a time, tried using 3 month old gpu drivers...but it all ends up the same...BSOD.

SO I'm stuck at the base Windows 8 with no way to update....what can I do?

Currently this is what I am running:

Intel Core i3-2100 Dual-Core 3.1GHz
GIGABYTE GA-Z68XP-UD3P F6 LGA 1155 Intel Z68
EVGA SC GeForce GTX 560 2GB 256-bit
CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3
