Unable to boot with gpu

[vincent-12345]

I need your help!

I bought an oculust rift and played 30-45 minutes until pc crashed. It turned black, no bluescreen. When i try to open my pc, i see the case fans spinning, but i am unable to see anything on my screen. My computer screen doesn't get any signal. I am only able to start my pc when gpu is unplugged and hdmi is in mobo. Is my gpu dead??

Probably so or that your PSU can't deliver the power the entire system needs with a GPU populating the system. Please list your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

What did you sue to tax the system with before it shut off? Assuming you're referring to "crash" as "the system rebooted".

I was using my oculust rift. I wasn't even in a game. I think my temps where fine. It was pretty basic use
