troubleshooting No Display: New MB, new Ram, new CPU

[xWanna]

Hey Guys,

 

I upgraded my system with the new parts. 
Now I have the problem, that the system won't boot or even show anything on the display.
When I power up, the RGB LEDs light up,  the fans start spinning and the Drives spin. The error LEDs loop through a few times and then the VGA stays red.

 

New Parts:

Gigabyte B550 Aorus Pro AC, AMD B550

AMD Ryzen 7 5800X 3,8 GHz (Vermeer) AM4

G.Skill RipJaws V Series, DDR4-3200 64GB, Dual Kit

Samsung 970 Evo Plus NVMe SSD

 

Old Parts:

RTX 2070 Super

EVGA 650W,80Plus Gold

 

I tried:

Checking all Cables.

Reseating the GPU a few times.

Reseating the CPU.

A different PCI-E slots.

My old GTX970.

One RAM-Stick in different slots.

Unplugged the Drives and non essetial cables.

Tried different Monitor cables and slots.

 

Thanks in advance for your help.

did you check if the mainboard already has a Bios to support Zen 3 Chips? You may need do download and flash a new Bios

not all bios support the 5800X

I assume yours was build a few weeks ago --> old bios. here you get a new one:

https://www.gigabyte.com/Motherboard/B550-AORUS-PRO-AC-rev-1x/support#support-dl-bios

 

The board has a option to flash the bios without a CPU. So you can try that (usually with a USB stick, formated on Fat 32) Never done it on a gigabyte only on Asus, but should be similar. In the Manual should be page which describes what to do.

 

edit: double check those links, if i posted the correct ones
