First, my specs. It was the first PC I ever built, and is 3 years old this month:

MB: AsRock M3A770DE
RAM: 2 x 4 GB Gskill Ripjaws
HDD: Hitachi Deskstar 1 GB
CPU: Phenom 2 X4 955 BE
PSU: Antec Neo Eco 620C (620W)
Old GPU: Nvidia GTX 460 (768 MB model)
OS: Windows 8.1
New GPU: R9 270X Radeon (HiS brand)

After installing the new GPU sometimes when I left my PC idling for like 45 minutes+ I'd come back and the screen would be a solid green (and the PC would be frozen). If I pressed the reset button after that the PC wouldn't boot up, I'd have to power everything off completely and then it worked just fine. It never did this to me while I was actively using it.

I did however get blue screens of death occasionally, and the graphics driver was almost always to blame whenever I looked at the logs. I got a weird error recently about win32k.sys as well, and when the PC tried to restart it kept saying it couldn't because the kernel was damaged (a hard restart fixed that issue). The bluescreen has been happening more and more lately, and I think the only thing that's changed is switching to the AMD beta drivers (the ones with mantle). I did try switching back to the WHQL ones which brought new problems!

I have:

* Run a memory test. No issues cropped up.
* Checked my hard disk.
* Used various programs to remove old GPU drivers (I think I was successful in purging the Nvidia)
* Reinstalled AMD drivers after purging all of the GPU drivers in safe mode.

After my latest purge, I can't even get windows 8.1 to boot with the AMD drivers installed. It would simply stall out every time on the loading screen. I had to go into safe mode and remove the AMD drivers. Right now I have no drivers installed and I'm trying to come up with an idea of how to proceed.

My thoughts on what could be the culprit:

* PSU not handling the extra power demands of the newer card well.
* On board audio playing badly with the Radeon (which don't those do some weird in card audio thing now?)
* Maybe I need to reinstall windows entirely? Unfortunately that's a cluster given that I have an upgrade key not a full win 8 license.
* Bad GPU from Newegg?
* Some weird motherboard thing... (I know nothing about MBs really)

Any help would be appreciated.
