My GPUs keep getting destroyed

I've used my computer for five years without any problems but last week my gpu (Zotac GTX 670) started making glitches (blue and green lines and dot's) up to not letting Windows start at all. Assuming it was the gpu I bought a new one Asus Strix GTX 1070 8gb. But after playing games for 1 hour it started making the same symptoms as the former one. I believe something in my pc is breaking down my gpus but have no clue of what it is. Most probably the PSU, but if it isn't... do you know if the motherboard is capable of burning a GPU?
I've tried installing in a different pci slot and also removing the RAM slots (one at a time), and reinstalling windows.
Any help would be greatly appreciated!

My build is:
Intel 3770k.
Motherboard Asus Sabretooth Z77
PSU Coolmaster silent pro 800w
Two 8gb Ram
Windows 7 64bits

Thank you very much!

And there is always the chance of getting a DOA power supply. In my over 30 years with PCs I have had exactly one motherboard failure and that was a faulty capacitor when everyone was having problems with them. I have had numerous power supply failures in that same time, including DOA ones. I have also had power supplies that seemed to work until they were placed under load when they quit working.
Troubleshooting is always hard, and without known good test parts can be even harder. More than once I have decided that a part was defective and replaced it with a new one...

most probably yes, but what if I buy a new PSU and it was the motherboard fault at the end. Is there any way to test which of both components is the faulty one?
