Random black screen while gaming and then crash.

So I just upgraded from a GTX 550 TI to a GTX 980 and since upgrading my computer will crash after 5-15 minutes of playing any game. The screen will go black and ill be able to hear some audio for a short period of time before it turns into a loud buzzing sound and then the computer resets. As soon as I log back in it gives me the "Windows Has Recovered From An Unexpected Shutdown" dialog. I tried several different fixes, I reinstalled all my drivers (doing a clean install), I've made sure they are the most recent version, I've replaced and tested the RAM (went and bought new RAM and tried playing with it, still crashes). I've taken the 980 out and put the 550 TI back in and tried to play the same games, no crashes whatsoever on the 550 TI. As soon as I put the 980 back in, crashes resume. I've tried a non-destructive reinstall of Windows 7.
And after a month of trying everything I can possibly find on it, I RMAed the card assuming it was a bad card. I finally got the replacement card from NewEgg just last week, and the first game I tried to play it did the same exact crash.
I figured it had to be some kind of driver issue, that somehow some old driver or something was still hiding somewhere on my install, so I did a completely fresh install, formatted the drive, and tried again.
Borderlands 2 went for 67 minutes before I decided to quit playing, and Call of Duty Ghosts went for ~30 minutes before crashing with the black screen and then resetting.

Here is the report that it gave me for the most recent crash:

==================================================

I attached the dump file in the zip below.

I've looked around and done a bit of research and another possibility I've heard of is that it could be a bad PSU? I don't think it's that the PSU doesn't have enough power, I've checked several PSU calculator sites to make sure and all of them say I could even make it by with a 400W

Here are the computer specs if they help at all:

Code:

CPU: AMD Phenom II x6 1045T @ 2.7GHz
RAM: 16GB 1600 DDR3, 8GB of G.Skill, 8GB of Ballistix
HDD: Western Digital 1TB 2.5"
GPU: PNY GTX 980
Motherboard: Asus M5A97 R2.0
PSU: 600W DiabloTek
Cooler: Corsair H110

Any ideas on what it could be? Did I just end up with another bad card? Should I replace the PSU? I honestly have no idea what else to do at this point.

That PSU outright scares the hell out of me. Apart from that...

PNY GTX 980 - Requirements: Minimum 500W or greater system power supply (with a minimum 12V current rating 42A).
Diablotek PSDA600 Output: +12V@40A.

Dollars to doughnuts, that's the problem. Your 550 Ti only required a 12V@24A.

Alright I'll see if I can get a hold of a new PSU. Would you recommend just another 600W but a Corsair or Coolermaster PSU instead? Or would you recommend a higher wattage just incase?

Also that DiabloTek PSU that you linked doesn't look quite like mine, I can't seem to dig up which one i have but mine looks exactly like this:



Not sure if it's an older model and would have different specs? But I can't seem to find it on DiabloTeks site =\

Okay so I have an old DiabloTek EL Series 600W that's why it looks different, I will look into a new power supply and that will probably fix the problem then. Thank you =)

It's more than likely that one has an even lesser 12V amperage than their newer series. So to figure how much wattage you actually need, use this. Be as specific as possible and don't forget to factor in capacitor aging as well (20-30% for a couple to few years). When in doubt, shoot for 750-850W (especially if you have any plans to upgrade your CPU later). 600W is now next to bare minimum for higher-end hardware. I would also have to recommend you aim for a higher-rated one. I stick to no less than 4-5 star end-user reviews no matter what, not just the technical specifications (really, most tech specs on PSU's are pure marketing if they don't have CE's to back it up). Also note that DiabkoTek's have a passive PFC; you really want an active PFC. Otherwise, you also want the new PSU to have a slightly greater than 42A on the 12V rail (I also always like to aim slightly greater than bare minimum requirements - better future-proofing). That amperage is just, if not even more, important than the overall wattage. And, sticking to a single 12V rail is also important IMO. You're welcome.
