Dodgy graphics card?

So about 2 months ago I got a ZOTAC Amp! GTX 1070 and it was fantastic (for a while). In the past few weeks I had experienced occasional unexpected restarts when playing under max load. Then, one day I start up a game and within a minute POOF, the video freezes (the sound continues playing) and the machine becomes unresponsive.

After rebooting, I get past the mobo bios logo screen and then BLAM, the machine hangs and there's a half-inch thick white horizontal band about 2/3 of the way up the screen, with a series of colored dots just above it. To me it looks like video card error artifacting.

I try the card in the other PCIE slots, switching the default slot each time, but no difference. So, I run my machine with onboard graphics for a few days while I try to troubleshoot the problem. After having no luck, I try the card in the original PCIE slot 1, and suddenly it's working again.

I'm just wondering if anyone has any clue whether this is truly a flaky GPU, or maybe a PSU issue (the random restarts made me suspicious), or perhaps indicative of something else? I've never had any problems with heat in my system so I ruled that out.

Specs:
- Windows 10 Home x64
- Gigabyte Z170XP-SLI-CF mobo
- ZOTAC Amp! Geforce GTX 1070
- Intel i5-6600k 3.5ghz
- 16gb RAM (g.skill ripjaws PC3000)
- Samsung 850 EVO 500gb SSD
- WD Blue 1tb 7200RPM HDD
- Corsair RM650x 650w PSU


Thanks in advance for any input!

I feel Brentoustine may be on the right track here, but another question worth asking is have you applied any overclock to your card? I had a similar experience with my 1070 from an overclock that was barely above stability...worked fine most of the time, but then something would send it askew...If you have applied any OC, just roll back to default for a spell and see if that effects it in any way. Just a thought and I would try the driver idea first.

Hope this helps!
