Faulty Graphics Card?

Greetings,

I'm running into an issue with my computer where during gaming sessions, the screen would go black and I would hear the fans of the GPU go loud and I'm forced to hard reset. If I re-seat the card, reapply thermal paste, or use a different driver version, I sometimes get the error that the display driver has stopped responding and has recovered instead of the black screen. After recovery though, I experience graphics tearing and I have to restart anyways.

My main computer specs are:

Intel i5 3570k @ 4.2 GHz
Asrock z77 extreme4
Seasonic X-Series X-850
Corsair Vengeance Blue 8 GB (2 x 4 GB) 1600mHz DDR3
MSI Radeon HD7870, R7870 Twin Frozr 2GD5/OC @ v13.4

I have ran memtest overnight with no errors, and then Prime95 and Heaven simultaneously overnight with no errors. The crashes only occurs when I have a game open, and it has never been consistent. Once, I was able to make it a full day without it crashing but after I turned it on and started playing the next day, it would crash.

When the crashes occur, the temperature, fan speeds, and GPU load are usually constant so I do not believe it is an overheating problem. The temperature of the GPU according to GPU-Z averages around 54c during my typical load, and 72c during a Furmark or Heaven stress test. The fan speeds are set to auto and vary between 30-40%. The load during the average crash is typically around 60%.

I have tried multiple things like replacing my PSU, reinstalling and using different drivers making sure I use Driver Sweeper in safe mode to completely wipe out the old driver before installing the new drivers, and underclocking the GPU clock and memory speeds by 100Mhz. I've also made sure that the drivers/bios for my motherboard is up to date. I've also tried reinstalling DirectX.

Unfortunately, I do not have another computer to test components on one by one.

It really confuses me that stress tests can't recreate the problem, but whenever I try to play a game that doesn't run my system at 100% load, I run into issues. Does that probably mean that the problem isn't hardware related, but how the entire system works together?

Any suggestions would be much appreciated.

I tried underclocking the GPU and the CPU, but at independant times. I used to run my i5 3570k at 4.4 but brought it down to 4.2. The GPU defaults at 1050/1200 and I tried it at 950/1100.

I brought the GPU back up to default after it crashed at the lower clock rate, while leaving the CPU at 4.2. I'll try to lower it down to 4.0 and see if it helps.
 
First try to down clock those on stock speed, if you see they are stable then its ok. Your CPU is good enough to run programs and games at a decent FPS, then why bother overclocking, you will not gain much.

After down clocking did you see any difference, are they stable? Good Luck.
