So basically building a PC is fucking hard apparently. Here's the problems: So basically, we plugged everything in to our PSU and motherboard. We plugged the ATX and CPU in from the PSU. We also plugged a VGA cable from the PSU to the GPU. There's also an AIO cooler and we plugged all those fans in. The fans (and the RGB) work fine. However, the GPU will not work at all. The fans at the bottom don't spin and I get no signal. Yes, I plugged the HDMI into the GPU and not into the motherboard HDMI. Also, we're not getting any USB power at all. If I plug in my keyboard it doesn't turn on. I've spent about three hours trying to get this shit to work
The motherboard is a MSI B550 Tomahawk and the GPU is a RX 6600 XT. The CPU is a Ryzen 7 5800X and the CPU is 750W (Gold I'm pretty sure) so I don't think it should have any problem powering the stuff. There's also a SATA and peripheral port. I don't have any SATA devices and am not sure what the peripheral port does so I didn't use it.
Any advice?
