So yesterday everything was working fine and I was smoothly playing 4K games but when I tried to start my computer this morning my screen wouldn’t get an input signal. After removing the GPU, the PC would start just fine. I tried both PCI-E slots various times and always ran into different issues.

The last time I tried booting with the GPU the Computer wouldn’t start at all but just turn on the fans and LEDs for 1-2 seconds and start going dark again (repetitive without me pressing anything). I was pretty sure it is the GPU but I also got the idea that the power supply might not be sufficient anymore (even tho I didn’t add any parts in the past 2 months).

Maybe someone can help me here?

specs:
Intel Core i5-7600K @ 3.80 ghz (water cooled H100i)
AsRock Z270 Mainboard
XFX TS550 (550 watt) 80Plus gold Powersupply
ASUS Dual fan GTX 1070 8GB

+2 SSDs and 2 HDDs

Im really hoping its the power supply but I have a bad feeling.
