GPU Fans stop spinning, Computer won't boot.

[bungeenick]

Got a new PSU and case for christmas, so I switched the components over and installed the new PSU. When the computer boots, the case fans and CPU fan start spinning and keep going, but after around 3 seconds the GPU (GTX 970) fans stop, and it dosen't output a signal. I don't know what is going wrong and preventing it from fully booting. A small LED on the GPU is turning on, so I'm almost positive it's properly connected to the power supply. The only new component in my PC is the power supply, everything else has stayed the same. When getting GPU out of old case, it required quite a bit of force, but I pulled straight up and went slow and steady, slowly pulling it out. If anyone can help me troubleshoot this I appreciate it!

Did you make sure that the pci-e connectors are connected? Also make sure that you have the nvidia drivers installed.

Pci-e is definitely connected, and I'm pretty sure that drivers are installed since it was working great in my old case with the other power supply.

Hmm, well it seems like it is power related. What connectors are there? 6-pin and 8-pin?

8 pin connector on the GPU, and the PCI-E was a 6+2 connector, and it's connected to the PSU with an 8 pin connector.

Does your display work if you connect it to the motherboard instead of the card? If it works, try to see if the GPU is detected using something like GeForce Experience.

I'll try to that when I get back home Friday, thanks for the help!

Figured out the problem, turns out a RAM stick was loose. I don't know why this caused these issues but once I slotted it in properly my computor works great!
