[Help] New system crashed and now won't get past the boot screen

So I have this new PC I just built, and it was working fine for several hours. It's a gaming PC, so once everything was set up I went ahead and I started up Skyrim. I had a few mods installed too and was looking forward to it.

Then some flickering in skyrim happened. The buildings and stuff that is. Then the whole screen went fuzzy and my computer crashed. When i tried to boot it back up, red-dotted lines appeared along the blackness of the screen that ASUS's logo was on. It offers to let be go to the bios, which it sometimes lets me do, and sometimes takes me there and the screen is all black except for the time clock, and when I move my mouse over a certain area. It also doesn't always boot at the same resolution.

I figured this was a GPU driver issue. So I tried using the disk that came with my GPU. When I try to boot it, it goes to a black screen and says: Reboot or select a proper boot device or insert boot media in selected boot device and press a key. Note: I did not install the driver disk on my first install of the OS. I just updated them from the website.

I have my driver disk in the disk drive, but when I hit a key it doesn't do anything. I already used it to boot windows and try a refresh on my pc so I know the drive works.

Here are my specs, and thank you for any help you can give :D 

OS: Windows 8.1

Motherboard: ASUS M5A97 R2.0

CPU: AMD FX6300

RAM: GSKILL RIPJAW X SERIES 8 GB DDR3 1600 mhz

GPU: NVIDIA GEFORCE GTX 760

HDD: Western Digital 1TB Caviar Blue

Looks like an issue with your GPU. 

You can't install your drivers from the boot screen. You need to be in Windows to do that. When you have a disc in the drive during start up it looks there and sees the media. It doesn't know exactly what it is, but it gives you the choice of booting off of it or your HDD. Remove it then try starting up.

 

I removed the drive disk and tried to boot. I wouldn't let me boot windows but gave me some repair options. I reinstalled windows, and it booted again. Once I logged in, I installed the drivers from the disk. It restarted, the same problem reocurred. It wouldn't boot windows at all the first three restarts (no signal to the monitor) and the fourth time it gave me repair options again.Would this be a hardware issue requiring a replacement GPU? Because I have no more ideas. 

It's most likely your graphics card. If you have a second graphics card try using it. Mabey borrow from a friend, or go to Best Buy and get the cheapest thing they have. It's probably the GPU though.
