Dead gfx card, bad PSU or something else?

I bought an r9 280 a couple months ago and it was working with no trouble. I put in many hours on a graphics-heavy modded Skyrim and Shadows of Mordor. Today, in the middle of a game, the sound cut out and the screen turned into 1/4 inch wide grey bars running vertically across the screen. I hard rebooted the computer and it loaded up to the Starting Windows screen like normal. When it transitioned to the login screen, everything was off color and glitchy. Once it moved to the desktop screen, it was only black.

I decided to start up in safe mode next and everything looked fine there, but when I transitioned back to the normal boot, the screen went black again.

Build:
PSU: Rosewill Green 630W
GPU: ASUS R9 280
CPU: i5-4590
MOBO: MSI Z97

Sounds like hardware failure. If you bought this a couple month ago, it should be in warranty. Ask for RMA and replacement for the manufacturer. If it's within a month, probably you can just ask for refund from the seller, though. Once I bought a GTX 460 at Microcenter, and had the simialr issue 3 weeks later. Although I already submitted rebate form - meaning that the box was cut already -, Microcenter refunded me full price minus the rebate amount, which of course I received from the manufacturer, Gugabyte, so no loss on me.

It could be the graphics card as already suggested, or the RAM.
This happened to me once, and when I opened the computer I found that the RAM was loose. I reseated it and everything returned to normal.
However, if the RAM is not seated properly, when you reboot the PC you get a black screen. So chances of it being the graphics card are more, since you're able to boot in safe mode.

Thanks, tried re-inserting the RAM on a hope and it didn't work. Looks like I'll be using the warranty on the card already.
