new build wont boot?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   hi all. new to building PCs and just finished my first build but it wont boot up. screen just says no signal. 

my build list is as follows

- ASRock b450 steel legend MOBO
- AMD ryzen 5 2600 CPU (Pinnacle Ridge)
- Corsair Vengeance LPX 16 GB (2x8GB) DDR4-3200 RAM
- SanDisk Ultra II 960GB SSD
- MSI GeForce GTX 1050 Ti 4GB GAMING X 4G GPU
- EVGA 650W 80+Gold Certified Power Supply
- Corsair LL120 RGB fans with commander pro
- Corsair H100i v2 Liquid CPU Cooler
- Lian Li PC-O11 Dynamic ATX Full Tower Case

when i turn on the power supply the MOBO leds light up but thats all, then when i actually press the power button on the case to turn the system on all fans and leds are on and running (including GPU fans and led) but the screen just says no signal, i have plugged my HDMI cable in the GPU and the MOBO but nothing, i also tested HDMI cable on my laptop and it works fine. i have read a few things about bios needing to be updated to work with newer CPUs? could that be my problem? the box that my MOBO came in says "AMD ryzen 3000 ready" "AMD 2000 ready" and "AMD raven ridge 2 ready"

any help would be tremendously appreciated

	the cpu works out of the box no matter which bios you are running a faultly board /bios will not display no signal with the system on or off i'm guessing the power connectors arent plugged on the gpu or bad case alignment making you think the hdmi is fully plugged

	Could be a bad GPU. My GPU that failed would give me a black screen.

	a broken gpu would still give a signal connection which is why i suggested gpu power or hdmi not fully plugged due to the case
