Question No signal on my new high-end Gaming PC

[edwestwick]

Hello guys, im new here and im coming here for a help. A few days ago I purchased the following components for my new computer.

Motherboard: ASUS PRIME X670-P
CPU: AMD Ryzen 5 7600X
Cooler: Be quiet! DARK ROCK PRO 4
Source: Cooler Master V750 Gold V2 White Edition
RAM: Kingston 32GB KIT DDR5 6000MHz CL36 FURY Beast Black RGB
Graphic card: MSI GeForce RTX 3080 10GB
SSD Samsung 980 PRO 1TB M.2 NVMe
Seagate BarraCuda 2 TB

The problem is, i have no signal via HDMI and via DisplayPort too. I tried the PC without graphic card and connected everything to motherboard HDMI and DisplayPort and still the same problem. I tried it with only simple RAM in one channel, same problem. RAMs are correct, they are plugged in A2, B2. The RGB lightnings working good, the fans runs great but no signal in my monitor. Does anyone have an idea what could be the problem? The only thing I can think of is a BIOS update, but I can't even do that because my system won't start. I tried removing the battery from the board, waiting, starting the PC but the same problem.

Thank you in advance for any help.

you wont have video from board this cpu dont have a integrated gpu so strip system to minimal parts and do you stil have a old gpu around for test in system in the same time made sure all parts been well seated on mobo .

I think youre wrong... the CPU have integrated graphic card (AMD Radeon Graphics - 2 200 MHz).

Zen 4 CPU's do have integrated graphics so you don't need a discrete GPU to get things going.

What you're doing seems to be correct, especially pulling the battery to do a CMOS reset. The best thing to do is go through all connections making sure they're fully seated. Sometimes taking everything out and doing a bench-test first is a good idea.

Keeping things simple helps: in addition to taking out the dGPU also try with only one stick of memory and even with SSD's and HDD's disconnected, so just the motherboard, CPU and one memory stick. Even move the memory stick to different slots. With no drives it should still POST directly into BIOS.

Does your board have a BIOS FlashBack feature? you don't need to boot the board or even get it to POST to update BIOS if it does. Check your manual on how to use it.

Guys, i tried today everything... we disconnect the HDD and SSD and still the same problem, we tried it with RAM used in first slot, still nothing. We disassembled everything, disconnected the processor, reapplied the paste and started the system, everything lights up but no signal... unbelievable, tomorrow I'm going to try a PC with another AMD processor to rule out a problem with the processor, if the system does not start even with the new processor, the problem will be on the board.

Zen 3 yes, you are correct. Zen 4, no.

Guys, problem has been found. I changed my motherboard to ASUS X670E-PLUS TUF Gaming and now everything works fine, but yes.. BIOS Flashback was needed.

Ah, great, glad you got it sorted!
