Problems Booting In

[Scarymonkeys]

So I just recently got a brand new GPU. (The G1 Gaming 960 to be exact.) I installed it, after a lot of problems, got the drivers; and it worked fine. I getting over 250 fps on Minecraft and one time I hit 303. Then I turned it off for the night. Next morning I turned it on to actually do some tests and my PC let me type in the password, then would freeze. I can't get to my desktop at all so I have to use the console. My father said that he did some updates last night and I'm guessing something didn't like it. I've gone into my console and whenever it tries to go to my desktop it says hda codec: out of rang cmd 0:7:707:ffffffff. I don't think it's my hardware as it was running fine before the updates. I am running Ubuntu 14.04 LTS. My system specs:

CPU: i3 4150

Motherboard: H97M Anniversary

Ram: 8GB Kingston Fury Series

HDD: 160GB WD Blue

GPU: G1 Gaming GTX 960

PSU; EVGA 500W B1

Anyone have some ideas on how to fix this?

Remove the GPU and try starting on the integrated graphics.

Alrighty, I'll have to try that out later. Is there a way to undo updates though?
