[SOLVED] Built my first pc and it doesn’t display anything? Please help me

[Itskasperrr]

So I just built my first pc today and started it up. All the fans and LED’s in my case turned on and are working fine. however when i plug my hdmi cable from my monitor into my gpu, nothing comes up and it simply says “no signal”. I have no idea what is wrong. Bear in mind I am very new to computers. My specs are as follows - CPU = Ryzen 5 3600, Motherboard = Asrock b450m hdv, GPU = RX 5500, SSD = 240GB M.2 WD Green, HDD = 1TB Seagate Barracuda, RAM = corsair vengeance 8GB DDR4 3000MHz and a EVGA 600 br 80+ PSU

never mind the USB and sata cables, just connect CPU 4 pin, Motherboard ATX 24 pin, GPU PCie cable, thats it, we just want to know if you even can get to BIOS at this point, no need for other cables

no, i can’t get to bios, i took out all the USB and Sata , and only used the ones you said, it’s still not going to the bios.

Did you make sure you have bios 3.10 version? could be on the box or on the website where you bought it. Becouse i was looking on local webshops, they all are 2000 series ready, so no good for your CPU

Or its the uncompatible ram

Yeah OP's board box has "AMD ryzen 3000 desktop ready”sticker on it.
