Question are these signs for a dead pcie or gpu

[Alquist]

I have a RX 470 that is giving black screen (no signal) with its fan going full blast but it doesn't go full blast at all times its like 2 times per 5 reboot. before that it would only work for a short period of time like 30 minutes only if its underclocked. Back to main problem, I plugged the monitor to onboard graphics while the gpu is seated to see if I get any image, weirdly I did but it was in lower resolution . Is there anyone that knows its possibly a sign of something? Coming to the testing it on another pc, im not able to do that as of now.

BaseBoard Product H81H3-M4
Installed Physical Memory (RAM) 16,0 GB
Processor Intel(R) Core(TM) i5-4460
Gpu XFX RX 470 Triple X

What is the make and model of your PSU and it's age? BIOS version for your motherboard? If you want to rule out your board with a faulty slot, drop in another GPU of much lower TDP to see if the issue persists. If you suspect the GPU itself, drop it onto a known working platform/motherboard and see if the issue persists.

tested it on another rig, same thing. I think its time for it to sleep unfortunately.
