Hello all!

Currently dealing with a potentially fatal PC issue. My PC was working fine, until an Xbox Wireless Adaptor was plugged into an Anker 4-port USB Hub located in one of the front USB 3.0 ports. Upon plugging it into the Hub, the PC immediately turned off and will not turn back on.

I have tried:
Removing the battery, clearing CMOS.
Disconnecting the front USB panel and booting.
Reseating all components.

I have not yet tested the power supply. Should also say that when I clear the CMOS, pressing the power button lights up the motherboard and GPU for all of about 0.2 seconds and the GPU fans spin about 1/8th of a rotation. After that, it becomes unresponsive again.

Does anyone have any ideas to what it could be as I've been using the front panel fine for the past 5 years and that USB Hub for about 2.

TIA to anyone who can help!

make and model of the psu?
full system spec?
Corsair CX500M

Intel i5 4670k
Nvidia GTX 970
MSI Gaming 5 motherboard
1xSSD
1xHDD

Interestingly. the PC boots and operates fine without the GPU in it. Running directly from the motherboard is faultless. As soon as I plug the GPU in, the PC refuses to boot, tried in both slots. PSU issue?
