1 year old system, specifications are:
i7 6700,
GTX MSI 1070,
MSI Bazooka 150M,
16GB Ram,
2TB HDD,
250GB SSD,
Windows 10.

I was overclocked at +100 MHz, +500 Memory Clock on my GPU, no issues with temps or anything whatsoever. Mid PUBG game my PC crashes, main monitor has green horizontal lines, second is disconnected. I restarted, launched game up, issue occurred again. Restarted again, issue occurred once again. I get rid of my OC, and that issue has disappeared.

Any ideas what’s going on?
GPU issue?
PSU issue?
Motherboard issue?

No idea what PSU I have, forgotten it,and I would have to take a part most of my PC to check as well.
