Hi. I've just put together a pc for my mum.
Msi b350 gaming pro
Ryzen 3 1200.
Gtx 1050 ti gaming x
Hyper predator 2x4gb
120gb Kinston SSD.
Coolmaster 500w PSU
Coolmaster 5 RGB case.

I've put it all together but cant get display the lights, leds and fans power up. But cant get display. Tried VGA and HDMI. The ez dubug says vga. But cant figure out why.
I've removed and swapped ram ports. Also tried without the graphics card.
Can't update the bios as I can't get it on.
I'm plugging it up to a TV not a monitor. That surely can't be the problem can it?
Stressing me out. My mum thinks I've done something wrong but I really can't see it.
Any help will be greatly appreciated
Cheers
Luke
