Random BSODs after Graphics Card Failure

Hey everyone,

This is my first post like this, but my meager skills don't seem to cut it.

I guess this all started with my old graphics card failing. It was time for an upgrade so I stuck an old spare in my system while I shopped and waited on shipping. The spare worked fine for about a month and then the day before my new card shows up my system BSODs.

I just assumed my old card went tits up so I waited till the next day and put the new graphics card in when it arrived(Radeon R9 270). Only to find out my power supply is 50 watts under par for my system with the new card. I disconnected my disc drive to save power and everything seemed to work fine. I updated to the latest drivers with Catalyst Control center and the PC seemed to work better than ever.

I ran Skyrim and LoL from Wednesday to Sunday w/o a hitch. Then I installed the new Elder Scrolls Online and within 3 hours had 3B stop code. My system BSOD'd quite a lot the rest of the day with random stop codes;

D1
3B
7E Referencing dxgmms1.sys
3B Referencing npsf.sys

I cleaned my drivers with Driver Fusion and re installed fresh drivers for the new video card, still getting BSOD. I plan on running a memtest overnight tonight and see if that comes up with any errors. I know my PSU being 50 watts under is no good, and I plan to remedy that immediately, but do ya think that's the source of my problem?

My PC seems to run perfect as long as I'm not loading up a Elder Scrolls Online, I work from home and put eight - 10 solid hours of data analysis on it every day without a hitch, It only seems to want BSOD when I want to get my game on.

If any of you lovely ladies and gents could point me in the right direction to get my system sorted out I would be in your debt.

Happy to provide any further information if needed.

More BSODs after I installed a fresh 700 watt psu. Updated graphics driver to beta and swapped out the HD Sata Cable to a new one and still getting BSODs. Here are the dump files from today;

This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.
