[SOLVED] New build not booting up BIOS

[kingupright]

So just got a new build started, Parts are:

Intel Core i7-9700K Coffee Lake 8-Core 3.6 GHz (4.9 GHz Turbo) LGA 1151 (300 Series) 95W BX80684I79700K Desktop Processor Intel UHD Graphics 630

CORSAIR RMx Series RM750x CP-9020179-NA 750W ATX12V / EPS12V 80 PLUS GOLD Certified Full Modular Power Supply

GIGABYTE GeForce RTX 2070 Super GAMING OC 3X 8G Graphics Card, 3 x WINDFORCE Fans, 8GB 256-Bit GDDR6, GV-N207SGAMING OC-8GD Video Card

CORSAIR Vengeance LPX 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) Desktop Memory Model CMK16GX4M2B3200C16

ASUS Prime Z390-A Motherboard LGA1151 (Intel 8th and 9th Gen) ATX DDR4 DP HDMI M.2 USB 3.1 Gen2 Gigabit LAN

Samsung (MZ-V7E500BW) 970 EVO SSD 500GB - M.2 NVMe Interface Internal Solid State Drive with V-NAND Technology

CORSAIR Hydro Series, H100i RGB PLATINUM, 240mm, 2 X ML PRO 120mm RGB PWM Fans, Advanced RGB Lighting & Fan Control w/ Software, Liquid CPU Cooler. CW-9060039-WW. Support: Intel 2066, AMD AM4, TR4

So got the build done, made sure everything was plugged in the right spot, 24Pin, CPU 8pin, etc. Powered it up and first thing i noticed was 2 fans weren't spinning. After reseting the CMOS, they worked just fine. Went ahead and plugged it into a monitor for the first time and theres no boot to BIOS. No display at all. Checked RAM for fully seating, tried onboard graphics vs GPU, Tried the CPU Jumper reset, tore down the entire PC and started from scratch again, same issue. At a loss but i feel its the Mobo or the CPU. Could use some advice or a second opinion. Thanks in advance.

UPDATE: Got a Mobo speaker to try and hear post beeps, that didn't provide any post codes. Triple checked the wiring, even compared the wiring and set up to my current build, and nothing out of the ordinary. I went ahead and ripped my old PSU out of current build and threw in the new PSU to try and see if that was the problem, but my current build started up just fine. If anyone has any other recommendations I'll hear them out but I believe I have a bad motherboard.

If you remove the RTX 2070 and use your integrated video adapter, does anything appear on screen?

The primary GPU would be the integrated so have you tried connecting the display to one of those?

You also need to be at a bios version at 1005 or greater to support that CPU. It came out April of last year .

Yes, I've tried a DisplayPort and HDMI ports on the motherboard versus the GPU with no result. I cant really update the bios (to my knowledge) without being able to see the BIOS. The monitor doesn't even detect my computer. Also i have checked that the monitor is set to DisplayPort and HDMI accordingly.

Did that, multiple times in fact, no change or display detection.

UPDATE 2: The Mobo speaker gave me no post beeps, so I went ahead and ordered a replacement for the motherboard. If this doesn't work I'm at a loss.

Update 3: Forgot to comeback for this, but it was absolutely the mobo. Got the replacement and it booted up just fine, Crisis averted.
