[SOLVED] "HDMI no signal!"

[Hellighax]

Hi.

Built a desktop for the first time - that is, I halfway did, cause there is no signal. I've gotten the image on the monitor several times now, but after various intervals the signal is lost ("HDMI no signal!"). I managed to go to BIOS and install Windows and started installing Steam and then I lost the signal (approx. 10 minutes). Prior I had an image for anything between 1-5 minutes. Soon I had no image. I removed the GPU and inserted it again. Now it worked...for some time (10 minutes or so). What seems to be the issue? Is the GPU not fully inserted or something? I don't want to press harder cause I already see the motherboard bending when I do. There is an additional cable which looks like this (https://www.techpowerup.com/img/KTLQ1w1XQvAKwf2p.jpg). Should I use that?

My config is this:

Cooler Master MasterBox NR200P.
ASUS G550-i Gaming (motherboard)
Corsair SF600 (PSU)
Ryzen 5 5600X (CPU)
ASUS RTX 3070 EKWB (GPU)
HyperX Fury DDR4 2x8GB
Kingston A2000

Thanks for any advice, greatly appreciated. I am sure some of you know the feeling of wanting that system up and running

Thats a PCIe riser cable,used to mount the GPU vertically,and they can get faulty.
Try the GPU in the motherboard slot,and good luck on draining the loop
