I've just completed my first PC build using the parts below, it powered up straight away but I'm not getting a signal when I connect it to a PC monitor or when I connect it to my TV with a HDMI cable.
CPU - AMD - Ryzen 7 1700 3 GHz 8-Core Processor
Motherboard - MSI - B350 PC MATE ATX AM4
Memory - Kingston - HyperX Fury Black 8 GB (2 x 4 GB) DDR4-2133
Storage - Samsung - 860 Evo 500 GB 2.5" Solid State Drive
Toshiba - P300 1 TB 3.5" 7200RPM Internal Hard Drive
Case - Corsair - Carbide Series 275R (White w/Tempered Glass) ATX Mid Tower Case
Power Supply - SeaSonic - 520 W 80+ Bronze Certified Fully-Modular ATX Power Supply
I don't intend to do any gaming so I didn't get a graphics card, but now wondering if I should have? I got a lot of the parts in the Black Friday sale for cheaper, so I did opt for the Ryzen 7 CPU, but probably overkill for what i'll use it for.
Have I missed something obvious or can anyone suggest what I may have done wrong please?
