So yesterday I was playing escape from tarkov, it was all running smoothly right until my pc shut off instantly with no warning. I tried to boot it back up and everything inside booted (CPU, FANS, GPU LED) however the monitor was saying no signal so I shut down the pc again and booted it up again but it remained the same. So then me thinking my GPU might of have died I plugged the DVI cable into the Mobo to try and use on board video and yet again it said no signal. So Then I tried that fix where you unplug the psu and hold down the power button for about a minute and that didn't work on both onboard video and GPU. After that I just took my GPU out and bam the on board video was suddenly working again and then I tried another GPU that is really old and doesn't have any PCI-E ports (AMD HD7700 1GB I think) so I'm guessing it uses the mobo power and that also worked. However my Current GPU that I've been using for about 3 years doesn't work (Sapphire Nitro RX 470 8GB) so I'm believing to think that this might be a PSU issue as this gpu does use quite a bit of power and I don't see why the On board video doesn't work with this GPU plugged but works when its not plugged in. I need some help with this issue so it would be greatly appreciated if someone would help me.Specs:AMD Sapphire Nitro RX 470 8GBI5 2500k8GB ddr3 1600mhz Ram (Single stick)1TB seagate hard driveCorsair vs650 power supply
