Rog Strix B550-I Gaming no boot

[Raphos]

Hi,

I just finished a new computer assembly with a Rog Strix B550-I Gaming.

The card is powered, the rgb lights from the jack connections are on.

I flashed the new bios (2803) with BIOS FLASHBACK. Seems to work, green led is flashing a few minutes and stops.

Unfortunately when I press the power button nothing happened. No fans turning, no QLED'S blinking on the motherboard.

I tried, CMOS reset, change power cables (CPU and sta for the aio), start the mobo with a jumper between PWRBTN pins.

The computer configuration :
- Power Corsair SF750
- Ram Crucial Ballistix BL8G36C16U4BL.M8FE1
- GPU Nvidia RTX A2000 12Gb
- Processor Ryzen 5900X
- Case Hyte revolt 3
- Aio NZXT Kraken X53
- Hard drive Firecuda 530

Could somebody help me please ?

Before putting everything back together, I would spend a few dollars on a stock cooler to test it out.

Merci zizipetasse for your answer 🙂

The problem is solved, thanks to read all the thread...

Run only one RAM module In the proper DIMM slot see if it will boot.

I did.

I was in contact with Asus support.

They told me to test the mobo :
- with the processor, one RAM module and the graphic card : no boot, no Q-LEDS.
- with the processor, one RAM module on one slot : no boot, no Q-LEDS.
- with the processor, one RAM module and change the ram slot : no boot, no Q-LEDS.

After I send the tests results, they told me to contact the vendor; there is certainly a problem with the mother board.

Hi,

I tested the processor this evening in another AM4 mother board, it's working.

So, I think my mobo is really bad...

I didn't flash anything this time as you told me.

I've flashed the bios with the first card because it was not working and I thought the bios was too old to support the Ryzen 5900X.

After booting the new card, I checked the bios version. It was the last version...
