Computer weird boot problems

[OnionRings]

So my sisters computer stopped booting, took a look inside and there was a blinking white light on the GPU which is a strix 570. The PC wouldnt do anything at all, no fans, just that LED. So I unplugged the 8 pin plug and then tried again and the LED turned orange/red (colorblind), so I figured something was up with it. I removed the GPU and tried booting without (iGPU) and the first time there was a blinking yellow/orange light top left of the motherboard by the ports. Tried again and it booted with no lights. So needless to say I think its the GPU but what could it be? I looked online and saw something about power issues but its worked fine until now, and it boots without the GPU so idk.

unplug everything, and pop out the watch battery on the motherboad for about 30 seconds. replace the battery and see if it boots up.

 

disclaimer: this will reset the bios to default settings

So I plugged the GPU back in and now its working fine, checking temps and what not now, what would cause this? Seating issue maybe?

well thats nice to hear, yeah could have been. maybe something bumped it pretty hard. I'd recheck everything is seated properly and call it a win

Yea will do, temps are mildly puzzling. Its low 70s right now with minecraft + shaders, which is the most demanding thing she does. Now 70 isnt a roaring inferno but its climbing steady and thats with the side panel off.

Yea she just hit 80 with the side panel so this might have been an overheat issue. Gonna give her an agressive fan curve.

Temps in check with fan curve but we plugged her xbox controller back in and the PC rebooted itself, then it got some weird green artifacting on the monitor. Thinking either the controller is at fault, or the USB port itself is shorted.
