[SOLVED] No logo gigabyte at start,no signal (newly build pc)

[pandemic00]

Hi I have recently bought all new pc components to build a new pc but i can't see the logo of gigabyte when booting,there is no beep sound, i can see light on my mobo, rear fan,cpu fan is working my computer screen shows no signal, cpu fans are working.I am not sure if the motherboard is defective. I would be grateful someone can help
monitor use display port (brand new monitor)

should i disconnect my cpu 8pins from mobo and try to start up pc?
maybe i could wrongly connect the front panel wire?

motherboard : Aorus b450 pro wifi (3000 ready on box )
cpu : ryzen 5 3600

even i remove both ram ,still same , no gpu installed

Do you have GPU ? Ryzen need GPU to show display. Except APU series with Vega onboard graphic.

no i dont have GPU installed yet, waiting for delivery. yes i didnot know ryzen need gpu , my last build was with intel 6-8 years ago.

Well, then like the car without a battery, you're not doing anything until you have one. You have no equipment that can display anything.

Yeah, Ryzen and Intel (with F series) need GPU. So you can't check it after you got some GPU installed.

Using the paste that already on the cooler surface ? Since the paste still new, I think that won't make any issue.

 

[pandemic00]

yes new paste applied on the brand new cpu/cooler surface

That's okay.

It is important to not use too much and if at all possible clean during each application. Being said ive done it myself a few times when necessary on tough to reach installations. Honestly its so important to have a good connection that its worth ensuring you have a solid connect even if it meant you waste 2-3 applications. I see it in a way of i rather spent a buck or two more on paste than constantly think about what if that is slowing my cooling. There are other ways besides paste, you can just get a thermal strip, not as popular as paste but strips can be reused over and over.
